sensiBel Unveils SBM140B Optical MEMS Microphone

eeNews Europe reports that sensiBel introduced the SBM140B. The optical MEMS microphone combines an 84 dBA signal-to-noise ratio with a 146 dB SPL acoustic overload point. It also uses 24-bit output. The resulting dynamic range reaches 136 dB. The tweet poses the question of a microphone that handles both the quietest sounds and extremely loud environments without switching modes. The attached graphic promotes the SBM140B product.
