If you have ever worked with a headset mic on an industrial phone system, you have likely experienced the dreaded "hissy" sound. This issue is most commonly caused by the microphone's sensitivity to mechanical vibration. In this article, we will discuss how to improve handset mic sensitivity for industrial applications.
What is handset mic sensitivity?
Industrial handset mics are designed to be very sensitive to pick up faint sounds. This sensitivity can be a problem when working with other audio equipment, as the mic will pick up background noise and cause issues with clarity. How much of a problem this depends on the specific mic and how sensitive it is, but it's always worth testing before using it in a production environment.
A crucial characteristic of every microphone is sensitivity, which is the ratio of the analog output voltage or digital output value to the input pressure. Given a known input, converting acoustic units to electrical units yields the magnitude of the microphone output signal.

Why is handset mic sensitivity important?
The sensitivity of phone microphones has a huge impact on the quality of voice calls. If you're making a call in a noisy environment, or if your phone's microphone is located in an awkward spot, your voice will be impaired. In addition, poor mic sensitivity can lead to missed calls and other frustrating communication problems.
There are a few things you can do to improve the quality of your phone calls regardless of the mic's sensitivity. First, make sure that your phone is properly calibrated. This will ensure that the microphone is picking up sound accurately and that background noise is not overriding your voice. Next, keep your hands free when you're talking on the phone. If you're holding your phone between your shoulder and ear, for example, the microphone will be less sensitive and may not capture sound as well as it would if you weren't holding the phone. Finally, if you're having problems with poor mic sensitivity, consider upgrading to a handset with a better mic. There are plenty of options available these days, so it's worth checking out different models to find one that works best for you.

How to measure handset mic sensitivity
Industrial handset mic sensitivity can be determined by measuring the dB SPL of the microphone input concerning the dB SPL of an audio source. This measurement can be made with a sound level meter and is often used in industrial applications to adjust the microphone sensitivity for optimum sound quality.
Without a lot of amplification, the high sensitivity will pick up the sound source. High-sensitivity mics perform best for ambient or room recordings since they can capture both nearby and faraway sounds. Low-sensitivity microphones frequently lose the quality of distant and quiet sounds.
