Wind noise reduction: Reducing the noise created by noise.
White noise generator: Produces sound comprising many frequencies together and is used effectively for tinnitus
Wireless technology – technology that allows the digital instruments to wirelessly communicate information
Wavelength – when a pure tone is produced, the sound radiates outward. As it does, different areas (of air) are in rarefaction and compression. Wavelength is the physical distance, generally measured in feet, between areas where the sound wave is in the same phase of vibration. For example, if air molecules are in maximal compression at one place, and then are rarefied one foot later, then maximally compressed again two feet away from that original compression place, then the wavelength is 2 feet. Wavelength is related to frequency and computed by dividing the speed of sound by the frequency.
Wax Loop: A small tool used by professionals and hearing aid users to clean ear wax out of the tubing of a hearing aid.
WNL: Within normal limits.
Word Recognition Score: The percentage of a list of speech stimuli that an individual is able to repeat.
