I enjoy listening to music at high volumes, but I'm concerned about possible long-term hearing loss. Articles covering this question suggest limiting audio volume to under 85 decibels.
Is there:
A setting built in to Windows or a third-party software that can control the system volume slider in units of decibels?
Or, a standalone third-party software that can limit audio playback by decibel level?
Or, a hardware device that I can use reasonably easily to cap audio decibel levels?
Without a calibrated system output, this is only possible with a feedback loop of somethine that measures the loudnes then adjusts/cuts volume based on the measured output. 1 watt could be 80dbor less or 100db+; so active control based on feedback would be the only way. – Damon – 2018-01-15T04:29:30.233
To add to Damon's comment, decibels is determined by the device that actually delivers the sound (headphones, speakers), your distance from it, and other factors. Computer speakers are typically self-powered, so the computer has little control over the sound pressure delivered to your ears. Decibels don't mean anything to the computer unless you introduce something to measure the sound at your ears and use that to adjust the computer's volume level. There is no OS setting or software that can do that, at least not without additional hardware, other than crudely, arbitrarily limiting levels. – fixer1234 – 2018-01-15T05:26:42.997
