Equal loudness spl hl decibel scale4/12/2024 ![]() ![]() This is because condenser mics contain active electronics and are more sensitive than dynamic mics. The microphone’s sensitivity is measured as its response to the 94 dB SPL signal.Ī common specification used in microphones and other audio-acoustic equipment is the max SPL.Ī microphone’s max SPL refers to the maximum amount of sound pressure that the microphone can handle (measured in dB SPL) before producing audible levels of distortion.Ĭondenser mics, for instance, typically have lower max SPLs than dynamic mics. Microphone sensitivitiesĪ microphone’s sensitivity is typically estimated using a 1 kHz sine wave at 94 dB SPL (equivalent to 1 pascal of air pressure). ![]() It’s also used in a range of audio-acoustic applications, such as for measuring microphone sensitivities. It’s measured in decibels (dB) relative to a pressure of 20 micro pascals.ĭB SPL is widely used for calibrating signals in hearing test equipment. It can be translated to other scales-dBA and dB HL-that are used to adjust dB SPL measures to account for the way that humans perceive sound at different frequencies.ĭB SPL is a measure of sound pressure levels in air. It’s widely used in the field of audiology, which deals with human hearing, and also in audio recording and listening applications. ![]() It’s measured in dB and is a standardized way of comparing the sound pressure levels of different sound events. DB SPL is a measure of sound pressure levels in air. ![]()
