Ancient whale skulls and directional hearing: A twisted tale
Skewed skulls may have helped early whales discriminate the direction of sounds in water and are not solely, as previously thought, a later adaptation related to echolocation. University of Michigan researchers ...

New test can screen all deafness genes simultaneously
Pinpointing the exact genetic cause of inherited deafness has always involved sequencing one gene at a time, a process that can take up to a year and cost roughly $1,000 per gene. It would cost around $75,000 to test all ...

Healthy ears hear the first sound, ignoring the echoes
Voices carry, reflect off objects and create echoes. Most people rarely hear the echoes; instead they only process the first sound received. For the hard of hearing, though, being in an acoustically challenging ...

Hearing impairment
A hearing impairment or deafness is a full or partial decrease in the ability to detect or understand sounds. Caused by a wide range of biological and environmental factors, loss of hearing can happen to any organism that perceives sound. "Hearing impaired" is often used to refer to those who are deaf, although the term is viewed negatively by members of Deaf culture, who prefer the terms "Deaf" and "Hard of Hearing".
Sound waves vary in amplitude and in frequency. Amplitude is the sound wave's peak pressure variation. Frequency is the number of cycles per second of a sinusoidal component of a sound wave. Loss of the ability to detect some frequencies, or to detect low-amplitude sounds that an organism naturally detects, is a hearing impairment.
