determining its suitability. One key factor is the Maximum Sound Pressure Level (SPL), which defines a microphone&#8217;s capability to handle loud sounds without distortion. What is SPL? Sound Pressure Level (SPL) measures the intensity of sound and is expressed in decibels (dB). Here are examples of sound levels for reference: What is Maximum SPL? The maximum SPL is the highest sound level a microphone can handle before reaching 0.5% total harmonic distortion (THD). The higher the maximum SPL, the better the microphone can handle loud sound sources without distortion. Why Does Maximum SPL Matter?
