What is digital hearing?
Digital hearing is a type of hearing aid that uses digital technology to amplify sound. Digital hearing aids are more advanced than analog hearing aids, and they offer a number of advantages, including:
- Better sound quality: Digital hearing aids can process sound more precisely than analog hearing aids, which results in better sound quality.
- More flexibility: Digital hearing aids can be programmed to individualize the sound settings, which can improve the user’s hearing experience in different environments.
- More features: Digital hearing aids often have more features than analog hearing aids, such as noise cancellation and directional microphones.
What technology do audiologists use?
Audiologists use a variety of technologies to assess hearing loss and fit hearing aids. These technologies include:
- Audiometers: Audiometers are devices that measure hearing thresholds. They are used to determine the severity of hearing loss and to select the appropriate hearing aid for the individual.
- Immittance meters: Immittance meters measure the function of the middle ear. They are used to diagnose conductive hearing loss and to assess the effectiveness of hearing aids.
- Tympanometry: Tympanometry is a test that measures the movement of the eardrum. It is used to diagnose middle ear problems and to assess the effectiveness of hearing aids.
- Otoacoustic emissions (OAEs): OAEs are sounds that are produced by the hair cells in the inner ear. They are used to assess the function of the inner ear and to diagnose hearing loss.
What is the difference between analog and digital hearing protection?
Analog hearing protection works by reducing the overall volume of sound. Digital hearing protection works by filtering out specific frequencies of sound. This can be beneficial for people who are sensitive to certain frequencies of sound, such as those who have tinnitus.
How does a digital hearing aid work?
A digital hearing aid converts sound waves into digital signals. These signals are then processed by the hearing aid’s microchip. The microchip amplifies the signals and then converts them back into sound waves. The amplified sound waves are then delivered to the user’s ear.
The microchip in a digital hearing aid can be programmed to individualize the sound settings. This means that the hearing aid can be adjusted to amplify specific frequencies of sound or to reduce background noise.
