Looks for Range (1/11)

  1. Interesting but apparently you have no idea how it works despite being an audio guy. it’s not an active filter. It’s a passive earmuff with a microphone and speaker. There is no “too fast and it sneaks by”. That’d be like you yelling and then apologizing because your mouth worked before your brain told it what volume to use. The microphone picks up the signal. The processor “processed” it, and the output waveform is sent by the speaker to the ear. You will NEVER have a 160db signal transmitted. It just doesn’t work like that. but to elaborate, and explain your confusion about signal speed, if a digital sampler is taking in a signal at 1 sample per nanosecond, and an impulse that was 1/2 a nanosecond hit at 200db, well, it simply wouldn’t sample that signal. It’d miss it. If it picked it up, it would (depending on the processing) attenuate it to the max allowed (120db maybe) or simply cut off the signal by not transmitting at all. It either clips the amplitude or it could turn off completely. in this case, of course, the passive muffs would only attenuate the 200db to about 175db. Thankfully it’s only for a half a nanosecond. incidentally, db matters for both sound level and duration! A 130db muffled gunshot isn’t as bad as a 120db 2-hour rock concert. OSHA even has times for decibels for acceptable exposure. bottom line, your electronic ear pro won’t “miss” a fast loud crack so your questions to the manfs about sampling rates is moot.
