How loud is loud, What DB is actually loud?

Bullot ,

Like your setup ...........

regards,

A quad ESl would not be the speaker for what you are looking to do. For me 90-95 db is very loud and i dont normally listen that loud a din. Normally 80-84 db nominal with peaks at or near to 95 db is about the loudest i like to listen at home.

Correct , 95 db in a domestic environment is very, very loud, even on crescendos.

Viggen900 , agree , most high sensitivity speakers suffer from uneven and exaggerated bandwidth IMO and most balanced speakers tend to be in the high 80's 88-89 being very good.

I wouldn't let sensitivity be the criteria for looking...

double speaker sq area and then doubling of power would result in a 6 db gain ...

Kijanki...

If you double the area and power remains the same , the increase is 3db or you half the distortion at the same db as one.

Play your system in mono, turn of one channel , guarantee you will have more than a 3db loss, even after factoring losses you will still have a 4.5-5 db min drop, the theoretical difference would be 6 db.

Tell the university guys there is such a thing as room gain ..

regards,

The 3 db gain is correct for free space ( anechoic) go ahead and measure your hi-fi system, with speakers l/r and with room gain it is more than 3 db, when you turn off one side from the listen position.

The paper Frank linked to takes interference effects into account (as distinguished from room reflection effects -- as you may realize they are two different things), and states that on average there will be a 3db increase, with a range between 0 and 6db depending on the interference effects at the exact listening position and frequencies.

Hello Al,

This is what i was alluding to when you measure using a typical 2 channel setup ( hi-fi application ) the localization and summation of both channels lead to 4.5-6 db increase in SPL from the listening position. The 3 db as per previously discussed only applies to free space.
