Abstract

For audiometric testing currently there are used special sound isolation booths. These booths shield the patients from sounds during the examination to provide a neutral and controlled atmosphere. The disadvantage of these sound isolation booths is the high space requirement and their immobility. So the usage of the booths is inflexible and restrictive. Because of the special and small design, some patients feel crowded and not comfortable. Furthermore, the installation of the booths has to be done by professionals.

A Method for a Portable Sound Pressure Deprivation Device

Idea: James De Finis, US-Piscataway, New Jersey

For audiometric testing currently there are used special sound isolation booths. These booths shield the patients from sounds during the examination to provide a neutral and controlled atmosphere. The disadvantage of these sound isolation booths is the high space requirement and their immobility. So the usage of the booths is inflexible and restrictive. Because of the special and small design, some patients feel crowded and not comfortable. Furthermore, the installation of the booths has to be done by professionals.

In the following a self-contained portable sound pressure deprivation device is proposed. This device shall be worn on or around the patient's head for the purpose of audiometric testing, seen in Figure 1. The proposed device shields the patient's skull and eyes against sounds and visual influences of the ambient environment without the need of isolating within a special booth. The shield shall also block any sense of feeling around the patient's head to prevent or reduce the chance of bone conduction from sound pressures. The device employs a combination of passive and active noise reduction technologies to create all or parts of the shield. Besides the pure-tone testing, the proposed sound pressure deprivation device contains the ability to immerse the patient into a virtual reality. So a virtual micro environment can be created by projecting single or multiple sources of sounds from any direction arou...
