Definitions

  • the present invention relates to a display device with effective sound level adjustment function based on hearing frequency characteristics of a user's age level.
  • Display devices are capable of applying predetermined sound enhancement blocks presented to users to enable them to enhance sound quality by selecting a sound preset. Basically, since each one of said predetermined enhancement blocks targets enhancing the sound quality of only a single sound content type, such an approach does not produce fully satisfactory results.
  • Parameters such as the position of the sound player, sound level, balance of the speakers and bass settings play an important role in sound performance of home cinema systems.
  • a condition affecting sound output quality is the sound frequency range which a user can perceive by hearing.
  • the number of vibrations generated in one second is referred to as sound frequency.
  • the unit of sound frequency is Hertz (Hz).
  • a human ear is capable hearing the sounds between 16,000 and 20,000 Hz.
  • the sound volume heard by an ear is referred to as sound intensity.
  • the unit of sound intensity is decibel (dB). Decibel is the lowest sound intensity which a human ear can perceive; a whispering sound is approximately 30 dB, a talking sound is in the range of 40-60 dB and a shout sound is in the range of 80-90 dB.
  • the frequency range which a person can hear narrows as he/she gets older.
  • WO2015144243 describes a method in which a new sound enhancement block is automatically selected or the current sound enhancement block is automatically updated in real-time according to the played sound content. By this, the perceived sound quality is enhanced without requiring any user intervention.
  • the present invention enables realizing an adaptive sound level adjustment system in which sound levels are automatically adjusted according to users' hearing frequencies varying by age, and a display device comprising thereof.
  • the display device realized to achieve the aim of the present invention and disclosed in the first claim and the dependent claims, comprises an adaptive sound level adjustment system enabling automatic sound level optimization by adjusting the sound level of at least one speaker.
  • the display device of the invention comprises said adaptive sound level adjustment system having an electronic control unit enabling determining a favorable sound level upon inputting of user age data, and adjusting and controlling the sound level of at least one speaker according to this sound level, and said at least one speaker driven in a sound level by said control unit. Sound level can thus be automatically optimized to present an enhanced sound quality.
  • the display device comprises an internal memory unit in which is stored operational data in the form of a database containing sound level values related to relevant age groups.
  • Said database comprises information regarding sound system settings required for generating favorable audiometric values by using age-dependent variation curves of human hearing perception.
  • the frequency values corresponding to age values are compared with a presaved database and a related voltage value is applied accordingly.
  • the display device comprises a device menu enabling inputting user age data to the system.
  • the menu may be designed suitably to enter commands by means of a remote controller.

  • the age information entered by the user by means of menu controls may be adapted to enable to enter information in different formats, such as numerical age information or birth date information.
  • the control unit activates the sound output in the frequency range favorable for the stated age data. If the sound output frequency is defined by the hearing intensity (decibel) measurement method depending on user age, than the sound in the frequency value corresponding to the determined decibel value is applied to the speaker. The user is thus enabled to enjoy the most favorable user experience by applying the sounds of values suitable for the user's hearing level.
  • the adaptive sound level adjustment system is activated upon inputting age data during normal operation of the display device, and compares the instant sound level with a threshold value predetermined according to the relevant age group. If the sound level applied to the speaker is below the threshold value, the speaker is applied a suitable voltage value for increasing the sound level in an offset level corresponding to the difference between the currently applied user defined sound level and the sound level suitable for the user's age group. The user experience is thus improved by providing a direct transition to the ideal sound level.
  • the display device determines the level difference for activating the value calculated according to the age group.
  • the frequency level change applied to nullify this difference is defined as the offsetting sound level.
  • the device control making selections through the menu, control of a device capable of commanding the display device may be enabled by means of a physical button on the controller device or on the display device, or by means of selecting on controllers defined so as to transmit commands to the display device upon being triggered by a point like buttons. Such a selection is transmitted to the electronic control unit which enables bringing the sound level automatically to the value calculated according to the stated age group. Making selection is thus facilitated for the user.
  • the display device comprises an electronic control unit enabling the device menu to input the user age each time the display device is turned on.
  • the user may activate this feature when he/she desires.
  • This feature can be programmed such that each time the display device is turned on, an age data input screen is displayed automatically. When it is not desired to use this feature, it can be completely turned off, preventing the age input screen from being displayed. This enables an application which can be customized according to user preferences.
  • the display device comprises an adaptive sound level adjustment system enabling grouping users' ages in three separate ranges, and assigning a separate sound level value for each group.
  • This segmentation may be formed depending on perceivable frequency ranges that are medically proven, differing in recognizable levels for groups which may be defined as young, middle aged and elder individuals. It is assumed that younger groups are capable of hearing frequencies in the range of 20 and 20,000 Hz, middle aged groups 20 and 16,000 Hz, and elder groups 20 and 8,000 Hz. In this case, sound output frequency in these three frequency ranges can be adapted for the age ranges defined for these three groups.
  • the users are thus enabled to protect their hearing health by being subjected to the sounds in the most ideal levels for their hearing capabilities, thereby improving their user experience.
  • the invention enables realizing a display device having an adaptive sound level adjustment system whose features and frequency ranges are optimized considering hearing functions of users.
  • the display device comprises at least one speaker and an adaptive sound level adjustment system enabling automatic sound optimization by adjusting the sound level.

  • At least one embedded speaker in electrical communication with said display device, emits the sound waves of the media received and displayed by the display device.
  • the display device is connected to various sound source devices such as a broadcast receiver set-top box, digital media player, or a game console by means of connection means such as an HDMI, Scart, or USB cable.
  • connection means such as an HDMI, Scart, or USB cable.
  • the display device determines the program type in a way known per se, and adjusts the sound frequency settings so as to select one of the predetermined equalizer settings corresponding to a sports event.
  • the response of the sound system in this case the sound system of the display device is changed by changing the equalizer preset, and the gain in a frequency band is adjusted.
  • the required settings are adjusted within the frequencies suitable for the hearing capabilities depending on age groups of people.
  • the display device re-calibrates the driving voltage of the speaker(s). By this, since a plurality of settings are adjusted taking hearing capabilities of the users into consideration, user listening quality is improved.
