A couple of years ago, after watching your videos, I bought an SPL meter. The first big shoch was how high the background noise level, in my small apartment. Like 48 to 50 dB in a very quiet complex, in a quiet suburban neighborhood. Next big surprise: how loud 75 to 80 dB peaks sounded.

Lowering the noise floor in any room increases resolution.

The information on this channel is absolute gold/chocolate & icecream !

Thank you for your support.

Thanks for the video. I have found that since I have gotten older I listen at 70-80dB SPL and seem to hear more details.

Quantity is never quality unless room resolution can deal with the increased amplitude of the presentation.

Yes, it helps! Thank u to you ❣

@@AcousticFields and on behalf of all your dedicated followers we appreciate your efforts and truthfulness in clarifying the erroneous information and claims swamping social media concerning room correction.

My listening/TV room is 35 dB or 37 with the HVAC fan on low. The lower the room noise, the louder your music seems at a given dB level I think. Very quiet suburban area, big lot. 70 dB is the general listening level. 80 seems quite loud. Contrast this with the car driving down a smooth road at 50 mph, which has an ambient noise level about 70 dB, and to make the music seem as loud at it does at 70dB at home, I'd have to crank it up to a level I wouldn't want to have it at very long.

With a lower noise floor comes higher resolution. You hear more using less energy. Its a win/win.

Hi Dennis still going strong, keep up the good work.

Just wondering if listening to a drum solo would be a good test of attack and decay? Nice point on volume levels. Good video again Dennis.

Look for instruments that have more tone. Look to piano.

Thank you so much 😀

Great points. You’re a fountain of wisdom. A side note, even at the risk of sounding too pedantic but I know you acknowledge you’re always learning… These symbols mean less than and greater than. Not less and greater. Saying sound pressure In fact, there’s no agreed shorthand to write what you are saying. Which is why you wrote it. A lot of people have settled on the arrow notation. As sound pressure *upright arrow*, resolution *downright arrow*. Obviously this isn’t easy to type out without emoticons but you have a blackboard. Hope this helps.

Stay focused on the ultimate message. We need more informed people.

Is controlled venting for your room an option for pressure control?

How do you use venting with waves of energy that are 34' long, 17' high?

Are you using a or c weighted measurements?

C is full range. You listen to music full range.

Dennise, I understand that higher SPL magnifies issues and is more difficult to pull off because it's less forgiving. Assuming however, similar sound quality, doesn't higher dB/volume reveal much more than lower db/volume?? In my experience the better the sound quality, the more I want to crank up the volume and play it loud. While with lower quality sound, turning up the volume can be painful.

As a general rule as pressure increases, resolution decreases. However, in a well treated room, you can add more gain without losing resolution over a wider SPL range.

And also I think our brain perceives dynamics better at lower volumes which is a win

@AcousticFields

Maybe. However if room resolution with its associated treatment is up to the task of managing higher amplitudes, you can have dynamics that are even larger in scope with same resolution with increaed amplitudes. Our theater rooms are designed to manage 105 dB SPL peaks. Our two channel rooms at 95 dB SPL. Neither lose resolution anywhere up to those levels, especially the dynamics.

My studio monitors have a switch. -95, -100db. I like it at 100db but with my interface level low, SPL reads 73 average. Speakers at -95 with interface level at 50% it just doesn’t “feel right?… Are there any guidelines?

@AcousticFields

Its dynamic range. You must decide what range to work within. I suspect the range will be dtermined by source content.

Man what is more important choising a wireless mic? Maximum SPL of the mic or higher Bit Depth value of the recorder/converter so 24 bit instead of 16 bit

Pressure levels that high will produce hearing loss. Nothing funny about that.
