Abstract

Audiometry is the testing to identify and diagnose hearing loss. Currently, special sound isolation booths are being used, which shield the patients from sounds during the examination to provide a neutral and controlled atmosphere for the audiometric test. The disadvantage of these sound isolation booths is the high space requirements and their immobility. Thus, the usage of the booth is inflexible and restrictive. Additionally, some patients feel crowded and not comfortable because of the special and small design of state of the art sound isolation booths. Furthermore, the installation of the booth has to be done by professionals.

A Method for a Portable Sound Pressure Deprivation Device

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

Audiometry is the testing to identify and diagnose hearing loss. Currently, special sound isolation booths are being used, which shield the patients from sounds during the examination to provide a neutral and controlled atmosphere for the audiometric test. The disadvantage of these sound isolation booths is the high space requirements and their immobility. Thus, the usage of the booth is inflexible and restrictive. Additionally, some patients feel crowded and not comfortable because of the special and small design of state of the art sound isolation booths. Furthermore, the installation of the booth 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, as depicted 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 isolation 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 around the patient's head. Additionally, the proposed device can produce sound vibr...
