Abstract

The present universal wearable computing device relates to a hearing assistance system, device, method, and apparatus that provide a discreet approach to user hearing assistance, without relying on a conventional hearing aid. The hearing assistance system and the requisite electronics may be incorporated into frames that also function as eyeglasses with earphone(s) that may be connected to the frame to assist user hearing. An earphone may be configured with minimal electronics, such that a power source enable sound transmissions to the ear, is provided by a connection to the frame of the eyeglasses. In another example, the earphone is configured without any electronics and sound is transmitted to the user/listener'"'"'s ear(s) via a psychoacoustic system. The sound quality of the transmissions to the earphones may be optimized using a tuning/equalizer application operating from a computing device, such as an app on a mobile device. The tuning/equalizer application can be used by the user/listener to optimize volume input levels to the earphone(s). The hearing assistance system may also protect from damaging environmental noise, provide heightened hearing capabilities, collect and process physiological and physical measurements, and provide communication capabilities for interacting with other computing devices.

a converter configured to convert and to amplify the audio signal to an amplified representation of the audio signal, wherein the converter is configured to adjust the audio signal to an audio level non-damaging to hearing functions of the user; and

a second transducer for emitting the amplified representation of the audio signal to a pair of earbuds coupled to ears of the user and removably coupled to at least a portion of the frame, wherein the earbuds are configured to block environmental noise from reaching the ears of the user.

2. The hearing system as in claim 1, wherein the earbuds are made of soft rubber that creates a seal with each respective ear to block environmental noise from reaching the ears of the user.

3. The hearing system as in claim 1, wherein the earbuds include passive noise-canceling padding and high-density foam to block environmental noise from reaching the ears of the user.

4. The hearing system as in claim 1, wherein the earbuds include active noise-canceling to mask low-frequency sound waves of ambient noise to cancel unwanted sound.

5. The hearing system as in claim 1, wherein adjusting the audio signal comprises adjusting amplitude of at least one audio parameter of the audio signal detected by the converter to be at a damaging level.

6. The hearing system as in claim 5, wherein the at least one audio parameter of the audio signal includes volume, frequency, and pitch.

7. The hearing system as in claim 5, wherein adjusting amplitude of the at least one audio parameter to a preferred non-damaging audio level selected by the user using an electronic interface to tune and equalize sound playback.

8. The hearing system as in claim 7, wherein the adjusted amplitude is stored as a preset, the user selecting the preset to set the adjusted amplitude when in an environment with damaging noise.

57. The hearing system as in claim 1, wherein the frame is configured with at least one sensor for measuring at least one of physiological functions of the user and physical surroundings of the user.

58. The hearing system as in claim 57, wherein the at least one sensor includes at least one of a temple area sensor for measuring the physiological functions and a capacitive touch sensitive area that the user touches with a body part for measuring the physiological functions.

59. The hearing system as in claim 57, wherein the at least one sensor measures the at least one of physiological functions and physical surrounds by use of at least one of electronic signals, sound pulses, light pulses, x-rays, odor detectors, accelerometer, and radiation.
