The Quest for Audiometric Zero

As with most sciences, there are some notable quirks in audiology, and the zero decibel point on the audiometer is one of them. Here is a brief history of the evolution of audiometric zero, the conflicting studies and controversies surrounding it, and how “0 dB” on the audiometer was ultimately established and standardized.

The Quest for Audiometric Zero

As with most sciences, there are some notable quirks in audiology, and the zero decibel point on the audiometer is one of them. In this article, Dr James Jerger provides a brief history of the evolution of audiometric zero, the conflicting studies and controversies surrounding it, and how “0 dB” on the audiometer was ultimately established and standardized.

Speech-to-Touch Sensory Device May Help Improve Hearing

In this current proof-of-concept study investigators hypothesized that they would be able to improve speech understanding under challenging conditions by exploiting the ability of the brain to integrate information coming simultaneously from different senses. They designed a minimalistic auditory-to-tactile sensory substitution device (SSD) that transforms low-frequency speech signals into tactile vibrations delivered on two fingertips.
