The 4061 Miniature Omnidirectional Microphone, Loud SPL can handle SPL up to 144 dB peak before clipping, making it one of the best miniatures for use on very loud sound sources, such as some instruments and human voices. It works well when used for hidden applications, for example mounted on the head or forehead of a theater performer. In this placement, the sound pressure level is about 10 dB louder than what you encounter with chest placement (lapel microphone).
