An oscillator is a device that produces vibrations. In audiology, an oscillator is used to deliver sound vibrations through the bone behind the ear, bypassing the outer and middle ear. This is called bone conduction testing.
What is an oscillator used for?
Oscillators are used to measure bone conduction thresholds, which can help to identify the type and severity of hearing loss. They are also used in auditory brainstem response (ABR) testing, which is a test of the inner ear.
What is a bone oscillator?
A bone oscillator is a small, handheld device that produces vibrations. It is typically attached to a headband that fits over the head. The oscillator is placed on the mastoid bone behind the ear to deliver sound vibrations through the bone.
Where do you put a bone oscillator?
The bone oscillator is placed on the mastoid bone, which is the bony prominence behind the ear. The oscillator should be placed as close to the ear as possible without touching it.
What are the 3 main components of a hearing aid?
The three main components of a hearing aid are:
- The microphone: This picks up sound waves and converts them into electrical signals.
- The amplifier: This amplifies the electrical signals from the microphone.
- The receiver: This converts the amplified electrical signals back into sound waves and delivers them to the ear.
