Definitions

  • the present disclosure relates to systems for promoting stress reduction. Specifically, the disclosure relates to systems using audio stimulation to reduce stress.
  • nap rooms i.e. silent rooms with a bed, couch or recliner to rest on. Such rooms help many people but some people are not much affected by spending time in a nap room and hence may consider other alternatives, such as taking time off work or simply continue working despite being stressed. Also, nap rooms are not available at all workplaces.
  • An aspect of the invention aims to mitigate the above-mentioned drawbacks by providing a system for mental stimulation using sound.
  • the system comprises a support device configured to support a human in a resting position.
  • the system also comprises a left idiophone and a right idiophone, wherein each idiophone is a percussion idiophone.
  • Each idiophone is provided with a respective striking device configured impact the respective idiophone upon activation of the respective striking device.
  • the system comprises a controller configured to repeatedly activate the striking devices.
  • the percussion idiophones emit a respective substantially pure-tone sine wave sound upon activation. The sound emitted mentally stimulates the human supported in the supporting device.
  • a left and a right idiophone enables one sound to be played from the left and another sound from the right of the human, simultaneously, thus enabling a wide range of soundscapes to be produced by a simple means.
  • Each striking device is controlled by the controller to repeatedly activate the respective idiophone by striking it, for example mechanically, electromagnetically, or pneumatically.
  • the repeated activation of the left and right idiophones enables continuous stimulation without human interaction such that the human being stimulated need not interact with the system and is thereby free to relax.
  • this system is used in an existing nap room but it could be used in any space.
  • the repetitive activation of the striking devices may be based on an activation strategy.
  • the use of an activation strategy provides a defined soundscape, for example by determining under what circumstances, when and/or how often the repeated activations are made.
  • the left and right idiophones may be tuned to emit sound in the frequency range of 220-280 Hz. Such frequencies are suitable for providing mental stimulation and relaxation.
  • the left and right idiophones may be differently tuned by 0.5 Hz but could alternatively be tuned to somewhere in the range in 0.2-7 Hz. Such tuning of the idiophones enables each ear of the human to receive a slightly different sound, which in turn provides further improved mental stimulation and relaxation.
  • the left and right idiophones may be positioned at opposite sides of, and at equal distance from, a vertical central-plane of the support device. Such positioning of the idiophones provides the same distance between the left idiophone and the left ear of a human supported as the distance between the right idiophone and the right ear of the human supported, independently of the length/height of the human. Thereby, this configuration enables the system to be used with persons of varying length with no calibration/setup-up between persons.
  • the idiophones may be attached to the support device or be attachable to the support device by attachment means. By attaching the idiophones to the support device, their position can be well controlled and not interfered with by humans using the system. This increases reliability of the system.
  • the activation strategy may comprise simultaneously activating the striking devices. By simultaneously activating the striking devices, both ears receive sound simultaneously and with the frequency difference corresponding to the tuning made.
  • the activation strategy may comprise repeatedly activating the striking devices with short enough intervals to avoid silence. Avoiding silence provides for continuous stimulation.
  • Each idiophone may comprise a vibration member being a metal rod.
  • the idiophone may comprise a pipe provided adjacent said vibration member in a position chosen for amplifying sound emitted by the vibration member.
  • the pipe amplifies the sound generated by the vibration member to achieve a greater effect with a small footprint.
  • the pipe may be aligned centrally along the length of the vibration member and oriented orthogonal to the vibration member. Such a position and orientation is suitable for achieving amplification of sound emitted by the vibration member.
  • the system may comprise a chamber provided with an interior space sized to house the support device and the idiophones in use, wherein the chamber comprises an entrance opening configured to allow a human to enter and exit said chamber, thereby gaining access to the interior space.
  • the chamber provides a private space for the human to enter for being mentally stimulated by the sound emitted from the idiophones. This enables use of the mental stimulation in otherwise crowded environment, such as an office space. Without the chamber, the idiophones would risk disturbing surrounding workspace and noise from the surrounding workspace would disturb the mental stimulation.
  • the entrance opening may be provided with a door or curtain movable between an open position allowing a human to enter and exit the chamber, and a closed position at least partly covering the entrance opening.
  • the door or curtain improves the privacy offered by the chamber by further limiting sight into the chamber. Also, the door or curtain improves the sound insulating properties of the chamber by reducing transmission of sound between the interior space and the surroundings.

  • an electric motor or a pneumatic system could in other embodiments be used instead of the solenoid 16 for moving the striking member 14 upon activation.
  • Yet an alternative to the solenoid 16 would be to use an electromagnet which upon activation of the electromagnet impacts the vibration member by magnetic force instead of accelerating a striking member 14.
  • Another alternative would be for a pneumatic system to pneumatically cause vibration of the vibration member 9.
  • some other drive means such as a spring loaded motor could be used which would enable use of the system 1 without connection to a battery or power grid.
  • the controller 7 is an electronic device configured to output one or more signals to control the striking devices 5, 6 in line with the activation strategy.
  • the controller 7 comprises a computer or microcontroller configured to operate by control logic according to instructions implemented in a software.
  • the control logic may also/alternatively be implemented fully or in-part in electronic hardware instead of software.
  • the controller 7 could alternatively be a mechanical device configured to operate using energy of position or using energy stored in a wound-up spring to thereby impact the respective idiophone.
  • An advantage of such a mechanical device would be that the controller could be used without connection to a battery or power grid by being given energy by human interaction before the relaxing treatment begins.
  • the controller 7 is setup to generate an output signal to the left 5 and right 6 striking devices simultaneously based on a fixed interval activation strategy but in other embodiments the activation strategy may differ, as described below.
  • the controller may be configured to receive one or more input signals and use the signals to control the output. Such signal may be provided from an external device and possible transmitted to the controller by means of a network connection, such as the Internet.
  • the left 3 and right 4 idiophones are tuned to emit sound in the frequency range of about 261 Hz and are differently tuned by 0.5 Hz, such as 260,5 Hz and 261 Hz respectively.
  • the idiophones 3, 4 Upon activation, the idiophones 3, 4 emit respective sound waves which together produce an auditory illusion in the form of a third sound perceived when the two different substantially pure-tone sine waves in the given range are presented to the listener dichotically.
  • the third sound would in this embodiment have a perceived pitch correlating to a frequency of 0.5 Hz which is the difference between the frequencies emitted by the respective idiophones 3, 4.

Description

SYSTEM FOR MENTAL STIMULATION USING SOUND
Technical field
The present disclosure relates to systems for promoting stress reduction. Specifically, the disclosure relates to systems using audio stimulation to reduce stress.
Background
Many people suffer from stress. To give people a chance to reduce stress, regain energy and improve focus, many organisations provide nap rooms, i.e. silent rooms with a bed, couch or recliner to rest on. Such rooms help many people but some people are not much affected by spending time in a nap room and hence may consider other alternatives, such as taking time off work or simply continue working despite being stressed. Also, nap rooms are not available at all workplaces.
Summary
An aspect of the invention aims to mitigate the above-mentioned drawbacks by providing a system for mental stimulation using sound. The system comprises a support device configured to support a human in a resting position. The system also comprises a left idiophone and a right idiophone, wherein each idiophone is a percussion idiophone. Each idiophone is provided with a respective striking device configured impact the respective idiophone upon activation of the respective striking device. Also, the system comprises a controller configured to repeatedly activate the striking devices. The percussion idiophones emit a respective substantially pure-tone sine wave sound upon activation. The sound emitted mentally stimulates the human supported in the supporting device. The use of a left and a right idiophone enables one sound to be played from the left and another sound from the right of the human, simultaneously, thus enabling a wide range of soundscapes to be produced by a simple means. Each striking device is controlled by the controller to repeatedly activate the respective idiophone by striking it, for example mechanically, electromagnetically, or pneumatically. The repeated activation of the left and right idiophones enables continuous stimulation without human interaction such that the human being stimulated need not interact with the system and is thereby free to relax. Preferably, this system is used in an existing nap room but it could be used in any space.
The repetitive activation of the striking devices may be based on an activation strategy. The use of an activation strategy provides a defined soundscape, for example by determining under what circumstances, when and/or how often the repeated activations are made.
The left and right idiophones may be tuned to emit sound in the frequency range of 220-280 Hz. Such frequencies are suitable for providing mental stimulation and relaxation.
The left and right idiophones may be differently tuned by 0.5 Hz but could alternatively be tuned to somewhere in the range in 0.2-7 Hz. Such tuning of the idiophones enables each ear of the human to receive a slightly different sound, which in turn provides further improved mental stimulation and relaxation. The left and right idiophones may be positioned at opposite sides of, and at equal distance from, a vertical central-plane of the support device. Such positioning of the idiophones provides the same distance between the left idiophone and the left ear of a human supported as the distance between the right idiophone and the right ear of the human supported, independently of the length/height of the human. Thereby, this configuration enables the system to be used with persons of varying length with no calibration/setup-up between persons.
The idiophones may be attached to the support device or be attachable to the support device by attachment means. By attaching the idiophones to the support device, their position can be well controlled and not interfered with by humans using the system. This increases reliability of the system.
The activation strategy may comprise simultaneously activating the striking devices. By simultaneously activating the striking devices, both ears receive sound simultaneously and with the frequency difference corresponding to the tuning made.
Further, the activation strategy may comprise repeatedly activating the striking devices with short enough intervals to avoid silence. Avoiding silence provides for continuous stimulation.
Each idiophone may comprise a vibration member being a metal rod.
The idiophone may comprise a pipe provided adjacent said vibration member in a position chosen for amplifying sound emitted by the vibration member. The pipe amplifies the sound generated by the vibration member to achieve a greater effect with a small footprint.
The pipe may be aligned centrally along the length of the vibration member and oriented orthogonal to the vibration member. Such a position and orientation is suitable for achieving amplification of sound emitted by the vibration member.
The system may comprise a chamber provided with an interior space sized to house the support device and the idiophones in use, wherein the chamber comprises an entrance opening configured to allow a human to enter and exit said chamber, thereby gaining access to the interior space. The chamber provides a private space for the human to enter for being mentally stimulated by the sound emitted from the idiophones. This enables use of the mental stimulation in otherwise crowded environment, such as an office space. Without the chamber, the idiophones would risk disturbing surrounding workspace and noise from the surrounding workspace would disturb the mental stimulation.
The entrance opening may be provided with a door or curtain movable between an open position allowing a human to enter and exit the chamber, and a closed position at least partly covering the entrance opening. The door or curtain improves the privacy offered by the chamber by further limiting sight into the chamber. Also, the door or curtain improves the sound insulating properties of the chamber by reducing transmission of sound between the interior space and the surroundings. Brief description of drawings

Detailed description
An embodiment of the system 1 will hereinafter be described with reference to the appended drawings. The system 1 comprises a support device 2 configured to support a human in a resting position. In this embodiment, the resting position is seated upright but in other embodiments the resting position could as well be reclined or laying down. The system 1 also comprises a left idiophone 3 and a right idiophone 4, wherein each idiophone 3, 4 is a percussion idiophone. Further, each idiophone 3, 4 is provided with a respective striking device 5, 6 configured impact the respective idiophone 3, 4 upon activation of the respective striking device 5, 6. Also, the system 1 comprises a controller 7 configured to repeatedly activate the striking devices 5, 6. The repeated activation is based on an activation strategy, but could in other embodiments alternatively be any repetitive activation. The activation strategy provides a defined soundscape for example by determining under what circumstances, when and/or how often repetitions are made, for each respective idiophone.
The support device 2 is a chair with adjustable back support. However, in other
embodiments, the support device may alternatively be a recliner, bed or similar piece of furniture.
The left idiophone 3 is to be positioned for being left of the human when the system is in use and could alternatively be named a first idiophone. The right idiophone 4 is to be positioned for being right of the human when the system 1 is in use and could alternatively be named a second idiophone. The terms 'left' and 'right' are hence merely a reference to the left and right of the person using the system 1 in a normal use position, as shown in Fig. 1. Idiophones belong to a group of analog musical instruments and percussion idiophones belong to a special sub-group of idiophones. A percussion idiophone is suitable for emitting a substantially pure-tone sine wave sound which after activation sounds a long time, such as 10-60 seconds.
Each striking device 5, 6 comprises a solenoid 16 configured to move a striking member 14 upon activation. The striking device 5, 6 is positioned such that the striker member 14 upon activation hits the vibration member 9. The striking device 5, 6 is attached to a support frame 15. In this embodiment, the striking member 14 hits an outer portion of the vibration member 9 but it could alternatively be configured to hit other portions of the vibration member 9. Alternatively, an electric motor or a pneumatic system could in other embodiments be used instead of the solenoid 16 for moving the striking member 14 upon activation. Yet an alternative to the solenoid 16 would be to use an electromagnet which upon activation of the electromagnet impacts the vibration member by magnetic force instead of accelerating a striking member 14. Another alternative would be for a pneumatic system to pneumatically cause vibration of the vibration member 9. As an alternative to an electric motor for driving the striking member 14, some other drive means, such as a spring loaded motor could be used which would enable use of the system 1 without connection to a battery or power grid.
The controller 7 is an electronic device configured to output one or more signals to control the striking devices 5, 6 in line with the activation strategy. The controller 7 comprises a computer or microcontroller configured to operate by control logic according to instructions implemented in a software. The control logic may also/alternatively be implemented fully or in-part in electronic hardware instead of software. In other embodiments, the controller 7 could alternatively be a mechanical device configured to operate using energy of position or using energy stored in a wound-up spring to thereby impact the respective idiophone. An advantage of such a mechanical device would be that the controller could be used without connection to a battery or power grid by being given energy by human interaction before the relaxing treatment begins. In this embodiment, the controller 7 is setup to generate an output signal to the left 5 and right 6 striking devices simultaneously based on a fixed interval activation strategy but in other embodiments the activation strategy may differ, as described below. The controller may be configured to receive one or more input signals and use the signals to control the output. Such signal may be provided from an external device and possible transmitted to the controller by means of a network connection, such as the Internet.
The left 3 and right 4 idiophones are tuned to emit sound in the frequency range of about 261 Hz and are differently tuned by 0.5 Hz, such as 260,5 Hz and 261 Hz respectively. Upon activation, the idiophones 3, 4 emit respective sound waves which together produce an auditory illusion in the form of a third sound perceived when the two different substantially pure-tone sine waves in the given range are presented to the listener dichotically. The third sound would in this embodiment have a perceived pitch correlating to a frequency of 0.5 Hz which is the difference between the frequencies emitted by the respective idiophones 3, 4. Such a soundscape is suitable for providing mental stimulation and relaxation.
In other embodiments, the frequencies could alternatively be in the range of 220-280 Hz with a tuned difference between left and right idiophone of 0.2-7 Hz.
Hence, for any embodiment, it is advantageous that the left 3 and right 4 idiophones are configured to simultaneously emit sound at different frequencies to dichotically affect the human user with an imaginary third frequency. However, a relaxing soundscape can still be achieved even with the left 3 and right 4 idiophones operating at the same frequency, although not as relaxing as when using differently tuned idiophones 3, 4 operating at different frequencies as described above.
The left 3 and right 4 idiophones are positioned symmetrically about a vertical central-plane 8 of the support device 2. The vertical central-plane is shown in Figs. 1 and 2 and runs centrally through the support device 2 along the length of the support device 2 as defined by the center of the seating position offered by the support device 2. Such positioning of the idiophones provides the same distance between the left idiophone 3 and the left ear of human using the system 1 as the distance between the right idiophone 4 and the right ear of the human using the system 1, and does this independently of the length/height of the human. Thereby, this configuration enables the system 1 to be used with persons of varying length with no calibration/setup-up between persons.
The idiophones 3, 4 are attachable to the support device 2 by attachment means in the form of screws. In other embodiments, other attachment means may be used or the idiophones may be integrated with the support device, or free-standing.
The activation strategy comprises simultaneously activating the striking devices. By simultaneously activating the striking devices, both ears receive sound simultaneously and with the frequency difference corresponding to the tuning made.
Further, the activation strategy comprises repeatedly activating the striking devices with short enough intervals to avoid silence. This is done by using a predetermined range of interval and a random function calculating a time within the range with varies slightly between each activation. The range is selected based on the knowledge of how long the idiophones sound after activation and the longest interval of the range is shorter than the time it takes for the idiophone to be silent. This may in turn depend on how hard the idiophones are struck or otherwise activated, and on the choice of material and shaping of the vibration member.
In this embodiment, each idiophone comprises a vibration member 9 being a metal rod. The rod has a square cross-section but could alternatively have other cross-sectional shapes in other embodiments, such as a cylindrical hollow pipe. A key aspect when deciding on shape and material of the vibration member 9 is that it should be able to vibrate at the intended frequency. In this embodiment, the vibration member measures 8*30*420 mm and is made of aluminium. In other embodiments, other materials, shapes and sizes of the vibration member could alternatively be used. Here, the vibration member is supported at positions corresponding to its vibrational nodes is its first mode of vibration, as known in the art of building and tuning idiophones. However, it goes beyond the scope of the present invention how to design and tune an idiophone to sound at a certain frequency and that is known in the prior art, such as in the article "Building a copper pipe 'xylophone'" by David R Lapp, The Wright Center for Innovative Science Education, Tufts University, which is incorporated herein by reference.
Each idiophone further comprises a pipe 10 provided adjacent said vibration member 9 in a position chosen for amplifying sound emitted by the vibration member 9, here, centrally of the vibration member between its vibrational nodes. The pipe 10 amplifies the sound generated by the vibration member to achieve a greater effect with a small footprint. The bottom end of the pipe is closed.
The pipe 10 may be aligned centrally along the length of the vibration member 9 and oriented orthogonal to the vibration member 9. Such a position and orientation is suitable for achieving amplification of sound emitted by the vibration member 9.
In an embodiment, the system 1 also comprises a chamber 11 provided with an interior space 12 sized to house the support device 2 and the idiophones 3, 4 in use, wherein the chamber 11 comprises an entrance opening 13 configured to allow a human to enter and exit said chamber, thereby gaining access to the interior space 12. The chamber 11 is built by any suitable construction technology and is preferably modular such that it can easily be disassembled to move the system between different locations, such as different offices, rooms, or floors. In the present embodiment, the chamber 11 is built from wood with wood fiber boards and sound proofing material inside its wall and ceiling construction. The chamber 11 provides a private space for the human to enter for being mentally stimulated by the sound emitted from the idiophones 3, 4. This enables use of the mental stimulation in otherwise crowded and/or noisy environment, such as an office space. Without the chamber 11, the idiophones 3, 4 would risk disturbing surrounding workspace; Also, noise from the surrounding workspace would disturb the mental stimulation. The entrance opening 13 may be provided with a door or curtain movable between an open position allowing a human to enter and exit the chamber 11, and a closed position at least partly covering the entrance opening 13. The door or curtain improves the privacy offered by the chamber 11 by further limiting sight into the chamber 11. Also, the door or curtain improves the sound insulating properties of the chamber 11 by reducing transmission of sound between the interior space 12 and the surroundings.
