There are quite a few apps available for measuring sound levels. I use 'Sound Meter' on Android. Obviously, this works for ambient sound measurement (speakers, environment). Anything below 90dB is "safe".How do you guys measure the loudness of your content? How do you measure when playing through speakers and how do you measure when playing through headphones?
I live beside the outer ring road and have to boost my system to 75% sometimes to be able to hear dialogues. I would love to assess how loud things are around me.
And what is the safe level to be in? I found this https://service.shure.com/s/article/maximum-spl-listening-levels-and-time-limits?language=en_US
If you are experiencing noise pollution in your surrounding environment, one suggestion is to use sound blocking sheets. This is usually marketed for professional use meant for sound recording studios.
