1. 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.
