Evolution of human hearing simulation
* Presenting author
Abstract:
More than 60 years ago, some of the first attempts was made to develop a simulation of the human hearing for objective measurement of devices placed close to the ear. The paper provides an overview of the ear simulators that have been develop over the years and outlines how numerous refinements have continuously improved the simulation of the human hearing. Some of the key features when dealing with hearing simulation involves the acoustic impedance and the geometry of the ear simulator. For the ear simulators that have been developed over the years these two features have been the primary focus in addressing the increasing need for realistic, accurate and repeatable acoustic measurements. This paper also presents a new and standardized fullband ear simulator that provides unprecedented realism in audio testing, reduces the development time for new acoustic product and ensures product audio quality in the marketplace.
