Abstract
Systems and methods to provide vocal acoustic attenuation for an acoustic sensor are disclosed, comprising attenuating an acoustic signal using an attenuation material covering at least a portion of a first surface of the acoustic sensor.
Claims20
A vocal acoustic attenuation apparatus comprising:
- an acoustic sensor having a first surface;
- and
- an attenuation material secured to the acoustic sensor and covering at least a portion of the first surface of the acoustic sensor,
- wherein the attenuation material is configured to attenuate a vocal audible decibel range from an acoustic signal received at a first surface of the attenuation material, and
- wherein the acoustic sensor is configured to receive the attenuated acoustic signal through the attenuation material and to provide an attenuated output signal.

A vocal acoustic attenuation method comprising:
- receiving an acoustic signal at a first surface of an attenuation material, the attenuation material secured to and covering at least a portion of a first surface of an acoustic sensor;
- attenuating, using the attenuation material, a vocal audible decibel range from the acoustic signal received at the first surface of the attenuation material;
- receiving, using the acoustic sensor, the attenuated acoustic signal through the attenuation material;
- and
- providing, using the acoustic sensor, an attenuated output signal.
