Sorry I don't mean to say you would never listen to anything at 112dB SPL, just saying when peak level at any frequency is at 112dB one likely would listen to much lower SPL, my measurement was just using the phone with dB meter app while I play some music so no steady tones for that sake. just wanna say that at music generally listening level should be well below 112dB SPL so should not be the limiting factor for almost all usecaseYou don't listen to continuous test tones. Momentary peaks especially in low frequencies are not loud at all. Threshold of hearing at 20 Hz is 70 dBSPL. If you are listening at 65 dB, you are not hearing anything at that frequency let alone it being loud!
Really folks, this whole dBSPL thing is so misunderstood it seems. What did you measure with it anyway? Noise? We are not talking about noise.
