Microphones: SPL & Distortion — AudioTechnology

WitrynaHowever, 0 dB on a hearing test is not the same as 0 dB SPL. Why? Because the human threshold to actually hear a sound is different depending on the frequency. So for example, at 1000 Hz, most normal human beings can not hear this frequency until it reaches 7.5 dB SPL. So, at least for 1000 Hz, 7.5 dB SPL is set to 0 dB HL (hearing … Witryna12 maj 2024 · Doug. Generally, A-weighted Slow mimics human ear perception the best. Slow doesn't 'catch' the transient spikes, so will give a lower number. The human ear gathers info over time, so super short duration spikes don't seem as loud. A weighted doesn't take the bass into account (Google A vs C vs Z weighting curves). Logged.
