Otometry Instruments

Additional Historical Information Related to Fitting Hearing Aids Using Otometry Test Equipment Otometry was based on sound pressure measurements and a damped wavetrain signal (DWT).  Because of this, instruments had to be devised to make these measurements.  An instrument was required to generate and deliver the damped wavetrain signals at the sound pressures required for different…

Otometry, Basic Concepts

Basic Principles for Hearing Aid Prosthetic Purposes Otometric principles, for hearing aid prosthetic purposes, deal primarily with the physics and acoustics of the hearing mechanism, requirements to identify otometry as a scientific approach to hearing aid selection. Last week’s post reviewed the differences between audiometry and otometry, setting the stage for this week’s further differentiation. 1. Prosthetic…
