Does It have to be loud?


Are you also under the impression that when people (or manufacturers) demo their equipment, they maintain sound pressure levels between 90-100 Dba. In general this is done in rooms being too small, and therefore the room will heavily interact with the sound heard in that room. Often, when you ask to lower the volume, the actual result is better, and –most likely- provides you with the information you were looking for. So, my question here is, do you also prefer to listen in the 90-100 dba range? Or do you –like myself- like to listen in the 70-90 dba sound pressure range? Of course, I’m referring to sound pressure levels at the listening position, which –in my case- is about 4 meter away from the speaker.

First of all, thanks all of you for your input. I do agree that it is more about dynamics rather that just loudness. Any continued SPL above 85 dba will result in hearing damage, so needless to say this is not recommended. My hearing –after 40 years running around on electricity power plants- is not very good anymore, Nevertheless, I’m certainly able to enjoy the music, and I love the dynamics. Unfortunately, not many systems are able to present the full dynamic range available. Most of the systems will run into distortion when playing 90-95 dba SPL at listening position.  Don’t be fooled, 95 dba is loud! Now, considering a background noise level of let’s say 40 dba, and a dynamic range of 50 db on a very good CD, your system must be able to produce undistorted SPL of 90 dba. That’s it. You may wish to have a bit headroom, but if your system plays SPL peaks up to 95 dba undistorted, you’re good. Believe me, not too many systems can. Other than that, I play music at a level which I believe would be natural. So if a singer would be standing in between the speakers, how loud could she/he possibly sing without amplification, that’s the norm for me. Of course, occasionally I do play louder, depending on the music. But hardly ever do I exceed the 90-95 dba peak SPL. (and yes, I measure with an Extech SPL meter, it does make a difference)

Many people are a tone of deafness that the reason they listen loudly
if these people consult an orl  surprise they don t hear middle and high frequency but especially grave
Soliciting opinions to this question....

I understand that doubling the power results in a 3db increase. Speaker manufactures typically include a sensitivity measurement *and* a recommended amplification power measurement.

Can one draw an inference as to the maximum spl capabilities of the speaker based on its sensitivity and recommended amplification level? I believe, "yes".

For example, if a speaker is rated at 93db sensitivity, and the recommended amplification is 20-200 watts, then could one infer that the speaker can produce (approximately) 115db "comfortably"?
