Definitions

  • the present disclosure relates generally to personalized sound delivery and hearing systems, and more specifically, relates to a method and an active, adaptive system for the enhancement of speech clarity at a distance or in environments with interfering background noise through the combination of audio inputs from more than one hearing device.
  • Hearing assistance devices such as hearing aids
  • hearing assistance devices include, but are not limited to, devices for use in the ear, in the ear canal, completely in the canal, and behind the ear.
  • Such devices have been developed to ameliorate the effects of hearing losses in individuals.
  • Hearing deficiencies can range from deafness to hearing losses where the individual has impairment responding to different frequencies of sound or to being able to differentiate sounds occurring simultaneously.
  • the hearing assistance device in its most elementary form usually provides for auditory correction through the amplification and filtering of sound provided in the environment with the intent that previously inaudible sounds become audible while maintaining comfort for more intense sounds while the device is worn.
  • Hearing aids employ different forms of amplification to achieve improved hearing.
  • ANC active noise cancellation
  • US2012/0250916 and WO2005052911 both relate to a hearing aid which can perform active noise cancellation.
  • the hearing aid includes a signal processor which produces a compensation/cancellation signal that can attenuate acoustic signals that bypasses the signal path of the hearing aid and enters the ear canal.
  • the hearing aid includes two microphones and a control unit provided for adjusting a time delay of the two microphone signals.
  • WO06003618 relates to an earplug with a circuit for active noise cancellation.
  • a noise signal is received in the earplug, a cancelling signal is processed by means of the circuit to cancel the noise signal.
  • U.S. Pat. No. 6,567,524 teaches a hearing protective earplug with an audio communication terminal for obtaining speech signals of high quality while attenuating noise. The earplug performs noise attenuation automatically adapted to the noise conditions and communication modes.
  • U.S. Pat. No. 6, 181,801 and U.S. Pat. No. 6,021,207 relate to a communications earpiece which receives audio signals, wired and wireless, respectively, sent from an external device such as a mobile phone. Ambient sounds are used for noise cancellation.
  • the communications earpiece can be used by both hearing impaired and non-hearing impaired users.
  • ANC anti-phasic, but equal amplitude sound is generated in the ear canal in an effort to cause destructive interference and thereby negate the presence of specific sounds.
  • An example would be found in noise cancelling earphones, wherein low frequency, periodic noises like multi-talker babble or aircraft engine noise can be identified, their level and spectral content in the ear canal (or under a headphone) can be captured and analyzed.
  • the phase path to the eardrum predicted, and a signal with equal intensity and frequency composition but 180° out of phase with the ambient sound is added, causing a reduction or elimination of the undesirable sound at the eardrum.
  • ANCs typically require a microphone located in the ear canal to capture and analyze the magnitude and phase of the signal, and an algorithm present in the system to allow for the process.
  • Various systems and methods are disclosed herein to combine electric audio signals from more than one hearing assistance device in order to enhance the ability to communicate effectively under adverse listening conditions through a process of adaptive constructive interference.
  • multiple users equipped with their respective hearing assistance devices may have the ability to connect to the individual devices of other local users in order to create a local area network of users who can then share acoustic information via a radio link for easier communication.
  • the hearing assistance devices of both users collectively receive more electric audio signals than a single hearing assistance device receives. Therefore, incorporating the electric audio signals with the acoustic signal from the vicinity of the user's device allows for enhancement of the desired sounds such as conversational speech relative to the background of less desirable sound.
  • electric audio signals received generated at the second hearing assistance device are transmitted to the first hearing assistance device and encoded as a replacement for input to a microphone channel located at the first hearing assistance device and combined with the signal captured by the second microphone on the first hearing device.
  • the combined electric audio signals are processed through a digital signal processor in the local hearing assistance device and adaptively time-shifted in order to enhance the amplitude of the desired signal via constructive interference.
  • the combined signal is then routed through a multi-channel compressor in the local hearing assistance device to apply gain and frequency shaping as appropriate for the hearing profile of the listener, converted to an analog signal in a digital-analog converter, and then transduced and output to the user' s ear.
  • a third hearing assistance device may be configured to receive electric audio signals from both microphones located at the first and second hearing assistance devices.
  • the electric audio signal from both microphones located at the first and second hearing assistance devices is combined and encoded as a replacement for input to a microphone channel located at the third hearing assistance device.
  • the electric audio signal received from the microphone at the third hearing assistance device may be combined with the electric audio signals received from both microphones located at the first and second hearing assistance devices.
  • electric audio signals from the second and third hearing assistance devices can be transmitted to the first hearing assistance device.
  • electric audio signals from the first and third hearing assistance devices can be transmitted to the second hearing assistance device. This approach can be expanded to encompass larger numbers of devices.
  • each hearing assistance device employs the other's microphone
  • each hearing assistance device is enabled to exploit the spatial differences between the two hearing assistance devices and environment noise.
  • this technique can be employed in non-acoustic hearing enhancement devices such as cochlear implants, bone anchored hearing devices, contact hearing devices, implantable hearing devices and in other methods of stimulating the auditory system.
  • a system may include a hearing assistance device (e.g. hearing aid) and an integrated control, for instance a mobile phone or computing device that is wirelessly linked to the sound delivery device.
  • the microphones on the sound delivery device and/or the associated mobile device may then detect sound levels at different locations at different times.
  • Significant data can be collected from different users to be aggregated and uploaded to a server for analysis to determine the current or average sound levels at particular establishments.
  • a database can be created that includes sound level and characteristic information for different cities, restaurants, sporting venues, public transportation, and others places.
  • sound level ratings may then be aggregated by a server in a database and accessed by users through an application on their mobile device, website, or through integration into websites that combine feedback on establishments.
  • GPS data can be tagged to the sound level data recorded through the microphones to identify the location.
  • signal-to-noise ratio, and time-stamp data maybe tagged to the sound level.
  • users can tag or indicate which establishment they are attending after receiving notifications on their mobile device or any combination of the tagging methods for confirmation.

  • FIG. 1 is a schematic block diagram of an exemplary hearing assistance device 100 that includes a hearing aid circuitry 101, an active signal enhancement system 102, and a wireless transmitter and receiver 103.
  • the wireless transmitter and receiver 103 is connected to an interface module 104.
  • the hearing assistance device 100 is connected to at least one other hearing assistance device to establish a secure, bidirectional, full duplex connection via the wireless transmitter and receiver 103.
  • the wireless transmitter and receiver 103 is configured to send and receive data via Near Field Communication (NFC), WiFi®, Bluetooth®, another wireless technology to other hearing assistance devices, mobile devices, tablets, laptops, computers, etc. Connection between the hearing assistance device 100 and other hearing assistance devices can be facilitated at the interface module 104.
  • the interface module 104 may include for example, mobile devices, tablets, laptops, computers, etc., equipped with a user interface.
  • the hearing assistance device 100 may connect to another hearing device via Bluetooth® pairing, facilitated by a user located at a mobile device, also paired with the hearing assistance device 100.
  • the wireless transmitter and receiver 103 may include a short-range wireless communication system, commonly known as Near Field Communication (NFC).
  • NFC Near Field Communication
  • the NFC circuit is a two-way communication circuit comprising both a transmitter and a receiver.
  • NFC is a mainly inductive communication system, which has a very short effective transmission range, such as approximately 5-6 centimeters. The protocol used for wireless near field communication via NFC is well described.
  • NFC enables a user to simplify the otherwise cumbersome Bluetooth® pairing procedure by temporarily bringing a mobile device comprising both Bluetooth® and NFC circuitry within the effective NFC transmission range of 5-6 centimeters of another device, which also comprises both Bluetooth® and NFC circuitry, e.g. an after-market headset, and then let the NFC circuits automatically exchange information between the devices, in order to perform the Bluetooth® pairing procedure of the two devices.
  • the two paired devices are separated again but will now be able to communicate via Bluetooth® or other method of transmitting and receiving digital audio signals, e.g. streaming audio to the head-set from the mobile phone and vice versa, as long as they are within the Bluetooth® communication range.
  • the NFC is used where the two devices are close together for exchange of critical pairing information, and after separation of the devices, it is no longer used for any communication between the devices.
  • the hearing aid circuitry 101 can include a signal path comprising one input transducer 203, e.g. a microphone.
  • the input transducer 203 can be pointed outward towards the ambient space surrounding the hearing device user.
  • the input transducer 203 can convert an ambient sound entering the ear of the user from the ambient space to an electric signal. Even though one input transducer is shown in the figure, it is understood that there can be more than one input transducer and more than one signal path.
  • the input transducer 203 generates electric audio signals, and sends the electric audio signals to a wireless transmitter and receiver 103 to send to a second hearing aid (not pictured).
  • the second hearing aid (not pictured) can send electric audio signals received from its input transducer to the current wireless transmitter and receiver 103.
  • the electric signal is communicated to the wireless transmitter and receiver 103, where it can be sent to another hearing assistance device.
  • electric audio signals can be received from the wireless transmitter and receiver 103.
  • electric audio signals from the transducer 203 can be sent to a gain stage 204 in which the electric audio signals are amplified. From the gain stage 204, the signal is communicated to an analog-to-digital (A/D) converter 205, which converts the amplified analog electric signal to a digital signal. The signal is then processed through an active signal enhancement unit 212.
  • A/D analog-to-digital
  • DSP digital signal-processing
  • the digital electric signal is communicated to a multi-channel compressor 202 in the local hearing assistance device to reduce the digital noise.
  • the digital noise reduction processing is applied to avoid amplifying undesirable, random environmental noise.
  • the enhancement of desirable signals occurs by the combination of the signal obtained at a remote location with the signal obtained at the local location. If the signals are appropriately time shifted to align the peaks of the signal, the result is a more robust representation of the desired signal, and theoretically no enhancement of the less desirable competing noise.
  • the combined signal is then routed to a digital signal-processing (DSP) unit 206 to apply gain and frequency shaping as appropriate for the hearing profile of the listener, converted to an analog signal in a digital-analog converter 207, and then transduced and output to the user.
  • DSP digital signal-processing
  • the digital signal-processing (DSP) unit 206 is adapted to process the digital electric signal in accordance with a desired correction of the hearing loss specific for the user of the hearing device.
  • the digital electric signal is communicated to a digital-to-analogue (D/A) converter 207, which converts the digital electric signal to an analog pulse density modulated (PDM) electric signal.
  • the analog electric signal is communicated to a multiplexer 208, and then to a low output impedance output driver 209.
  • the analog PDM electric signal can be communicated to an output transducer 210, e.g. a speaker within the ear canal, which converts the electric signal to a sound pressure signal affecting the tympanic membrane in the residual volume of the ear canal (not shown).
  • Figure 2 also exemplifies the active signal enhancement unit 212 of the hearing assistance device 100.
  • the signal enhancement system 102 improves signal to noise ratio by increasing the amplitude of the desirable signal via proximity and constructive interference while relatively preserving the undesired background noise (which is typically assumed to be diffuse and effectively random). Digital noise reduction processing is applied later in the chain to attempt to avoid amplifying undesirable, random environmental noise.
  • the enhancement of desirable signals occurs by the combination of the signal obtained at a remote location with the signal obtained at the local location. If the signals are appropriately time shifted to align the peaks of the signal, the result is a more robust representation of the desired signal, and theoretically no enhancement of the less desirable competing noise.
  • the signal enhancement unit 212 may be configured to enhance speech clarity at a distance or in environments with interfering background noise through the combination of audio inputs from more than one hearing device. Noise may be unwanted audio signals that disturb the hearing device user.
  • the remote microphone is able to capture the desirable signals and the effect of time aligning peaks in the two or more signals results in an enhancement of signal magnitude. Therefore, the speech intelligibility of sound sources that are at a distance from the talker and the listener (e.g., in between or to the side of the two) is enhanced, as the signal is enhanced via constructive interference and proximity effects, while the noise, being random, is not.
  • both the electric audio signals from the microphone located at the first hearing assistance device and the electric audio signals received from the connected one or more hearing assistance devices are combined.
  • the combined electric audio signals are processed through a digital signal processor in the hearing assistance device to enhance the amplitude of the desired signal via constructive interference, at step 308.
  • the magnitude of the desirable signal is increased via proximity and constructive interference while relatively preserving the undesired background noise.
  • the combined signal is then routed through a multi-channel compressor in the local hearing assistance device to reduce the digital noise.
  • the digital noise reduction processing is applied to avoid amplifying undesirable, random environmental noise.
  • the enhancement of desirable signals occurs by the combination of the signal obtained at a remote location with the signal obtained at the local location.
