836 Development of a device for acquisition of utterance information in the noisy environment by measuring vibration generated on a body surface
Details
Development of devices enabling communication under the noise environment such as disaster sites is an important matter. In this study, a communication device was developed using a PVDF film. Its ability in voice acquisition was tested in high noise environments. The results suggest that the PVDF film sensor was able to shut out the environmental noise and was able to acquire the voice signal up to approximately 4 kHz. Moreover, the voice data measured with the PVDF film sensor was clearer than those with the conventional microphone.
