Validation of a Virtual Sound Environment System for Hearing Aid Testing
نویسندگان
چکیده
Hearing aid (HA) users typically benefit a lot from their HAs in simple acoustic situations like a one-toone conversation in a quiet room, but they have difficulties following a conversation in challenging listening situations involving multiple talkers, background noise and reverberation [1]. The processing power of HAs has increased dramatically over the last 10 years and advanced signal processing strategies have been applied to help the users, particularly in more complex listening situations. To assess and evaluate the performance of such modern HAs, the test scenarios should be as realistic as possible. Until recently, however, most testing was done either in very basic conditions with simple loudspeaker setups in acoustically dampened rooms or in field studies, where end users wear certain types of HAs for a while and report back via questionnaires after the testing period. The first approach offers much control over the test conditions, but only very limited flexibility regarding the acoustic conditions. In field tests, the participants experience the HAs in their everyday life, but the experimental conditions are difficult to control.

The sounds present in our environment aid us in determining the distance and direction to objects and provide us with detailed information about our surroundings. In order to enable the user of a virtual reality system to be fully immersed in the virtual environment, the user must be presented with believable sensory input. Although the majority of virtual environments place the emphasis on vis...

In general hearing tests are necessary to assess the properties of spatialisation systems. To speed up the procedure of testing different system parameters an objective model of localisation in binaural sound reproduction system is introduced [7]. In the following the localisation properties of an auditory system based on playback via head phones is investigated. Therefore a new design for the ...
متن کاملDevelopment and Validation of Sound Transmission Loss Measurement System for Measuring Muffler Performance
Muffler is a part of the vehicle exhaust system that absorb or reflect sound waves to reduce exhaust noise. One of the most important determinants of a muffler performance is the amount of attenuation that has on its input wave; this parameter is known as sound transmission loss. Four - mic standard test is one way to determine this parameter which is used in this paper. In this study, a test d...
