MEMS microphones offer a high-quality signal at low cost. MEMS manufacturing techniques ensure a high consistency of their parameters from one microphone to another. They are extremely stable over time and temperature. Their high-frequency resonance must be counteracted precisely to get a spectral sensitivity that is accurate enough for a type I SLM.
