An electroacoustic device that generates tones throughout the audible range (usually at each octave between 125 Hz and 8 kHz) at amplitudes related to the expected thresholds for a normally hearing person, and presents them to a patient, typically one ear a...
An electroacoustic device designed to measure the hearing threshold of a patient by presenting tones of increasing or decreasing intensity through headphones to establish the level at which the patient first becomes aware of the sounds. The device automatic...
An electroacoustic device designed to be used in a clinical setting to measure the hearing threshold of a patient by presenting tones of increasing or decreasing intensity through headphones to establish the level at which the patient first becomes aware of...
A device that is worn on the head, typically fitting over both ears, but that may fit over one ear. It supplies the user with audio input increasing the sound volume of, e.g., television, radio, or a communication amplifier.
An electroacoustic device designed to measure the hearing threshold of a patient by presenting words of increasing or decreasing intensity through headphones, which the patient is required to recognize and repeat, to establish the hearing capacity of the pa...
An electroacoustic device designed to measure the hearing threshold of a patient by presenting tones of increasing or decreasing intensity through headphones to establish the level at which the patient first becomes aware of the sounds. Changes in tone inte...
An electrically-powered assembly of devices designed to treat tinnitus through bimodal neuromodulation of the brain, involving simultaneous application of electrical pulses to the tongue and delivery of specific sounds to the auditory system. It includes a ...
A mains electricity (AC-powered) audio device intended to improve the listening experience of a person who has difficulty hearing or who is hearing impaired by creating ultrasound-directed sound waves targeted at the individual without the need for earphone...
