loudness

I've tried to do a simple experiment with my phone. there's an app called Decibel X on google Playstore. It works like a Decibel meter. I've watched a video on youtube and it seems kinda accurate or at least close to accurate. I tried to play music with my headphones and the music averaged at 75...

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...

APU Loudness Contour is a real-time equal-loudness filter that offers precise control over a wide range of perceptual loudness contours, including ISO 226 (2003 & 2023), Fletcher-Munson, K-weighting, A/C-weighting, ECMA-418, and ITU-R 468. Each contour is normalized to 0 dB at 1 kHz and...

hi somedays ago i was looking for audiophile albums , and in the list there is Lorde 's Melodrama i don't know if the list is related to cds or vinyls (just because in vinyls I guess they could not make play too loud ) well since I own Lorde 's Melodrama cd , I have ripped in flac with...

Our MiniDSP Flex has four presets but we use only one: Julian Krause's target from the video where he shows how to use REW to make measurements and produce parametric eq specs. I don't think we've ever had better sound but it makes sense to play around and maybe learn something more about our...

I own the Yamaha r-n2000a which has a loudness adjustment. It sounds like it adjusts the mid frequency to my ears, but I can not tell for sure. Is there a way to look at the specs to find out what exactly the loudness adjustment knob changes?

For a long time I can not deal with one super problem that everyone knows, but no one understands (at least in our super country Russia) as the main reason to solve it. Games/movies use (or have) a wide/high dynamical range in sound. It looks like this: there is a dialogue in the film and then...

Adding EQ will put a burden on the amplifier, but how can I calculate the specific dB impact of the EQ settings on the overall maximum volume? Thank you!

Hey, I have seen the usual lists like https://www.hearingconservation.org/assets/Decibel.pdf about how loud various sounds are. But I'm having a hard time to understand how loud music would be with those numbers. What I'd really love to see is a table showing the SPL levels for music...

Does anyone have some example measurements as to how typical speaker FR changes with volume? I know that Amir test speakers at 86dB and 96dB, but how does it work at low volume? The reason that I am asking, is a discussion I've seen on which speakers/hifi equipment sounds best at low volume...

Hi all, Not sure if this is the correct section, but it makes the most sense (unless I am corrected). I've a few loudness meters to use in the DAW, but nothing that can scan an audio file and provide a nice graphed plot. I knew ffmpeg could utilise the ebur128 audio filter to generate all the...
