safety

I'm reaching 30 and worried if my listening level has been too loud, so I want to estimate my headphone listening loudness. But not exactly sure how. I listen on iPhone 13 + Lightning dongle + Etymotic ER4SR. The iOS volume slider position is usually at 1-2 notches louder than the middle...

I was wondering whether it would be safe to use an audio interface (with an electric guitar or keyboard or microphone plugged in without any EQ or compression) with active or passive home audio speakers such as KEFs or Revels. Speaker companies have told me not to do this multiple times; one of...

I have a vintage Denon turntable, which has two earth leads, tonearm earth wire associated with the RCA leads, and a chassis earth wire (with a small spade, like the tonearm earth wire). I feed the turntable AC via a 240 three pin -100V two pin isolating step-down transformer, as Japan model...

Hi everyone. First-time poster here. Since my latest hyper-fixation is reading audio equipment measurements I decided to make an account here on ASR. For years I’ve been using my trusty Behringer UM2 USB audio interface for my DAC/Amp needs. This thing boasts a whopping (!) 16bits/48kHz...

These results are superimposed from the PTA audiogram test I had and it looks like I have low-frequency hearing loss in both ears (13dBHL right ear and 12dBHL left ear), and my right ear has lost some high frequencies. This makes me wonder, how long can use IEMs and headphones until it reaches...

Heya, there's a couple of threads asking about safe listening levels and people asking about voltage/power requirements in almost any amp/headphone thread. Here's my take on this: Noise Exposure Limits The EPA and WHO recommend that noise should be kept below 70 dBA over 24 hours and below 75...

Say there is a device that supplies ~54v of phantom power instead of the conventional 48v. If one plugs Cloudlifter, FetHead, etc. into the chain, can these be damaged by the excess voltage?
