How loud is 93 decibels?

Asked by cadetjoecool (218points) December 28th, 2011

So I got these computer speakers for Christmas and it says that the sound pressure level is 93 dB. I had the volume up half way and they were already pretty loud. I don’t want to push them past their limit, so ya. How loud can they go without suffering damage?

P.S. They’re Altec Lansing VS2621

Thanks a bunch! :)

Here’s a comparison chart.

At 90 and above the chart says “sustained exposure may cause hearing loss.”

(I goggled this. it was easy to find.)

Also, the scale is logarithmic. If I remember correctly, every time you go up 10 decibels, the loudness doubles.

Laugh. 93 dB is Looooud! It includes sounds like an old dialphone ringing and a motorcycle.

This grid will give you pictures of sounds in that audiological range.

I work in a machine shop. The machine I run most of the time is an OKK 50-taper CNC milling machine that takes up about the same floorspace as two parked cars. It cuts steel and titanium quickly, and makes enough noise in the middle of a heavy cut that you can hear it through the walls and out on the loading dock 100 feet away, When it chatters, I wince despite wearing earplugs.

That machine clocks in around 90dB (just enough to require hearing protection) during our OSHA audits.

You’ll damage your ears before you damage the speakers.

@PhiNotPi It is logarithmic. 10dB is a tenfold increase. Doubling loudness is ~3dB (3.01 to be exact) increase.

90dB is too much!

It’s very,very loud. The airplane noise has 130 decibels.

The table in the following link gives you an idea of relative loudness for sound pressure level:

Average speaking voices are around 72dB-SPL; 90dB-SPL is more than 100 times louder!

The measurement of “93dB” is most likely an electronic measurement for the total dynamic range (maximum output level) of the speakers (at full-tilt). Most likely, you listen to them much lower than that maximum.

There are actual SPL meters you can buy at places like Radio Shack that measure sound output in the air (acoustic sound pressure level). The scales between electrical and acoustic are the same scale, but use different reference points to call “0” or normal.

At school this year, we learnt that anything above 80 decibels is enough to cause permanent hearing loss. The affects may not be immediate, but will occur in the long term, like when you get older.

93 decibels is perfect for me, up the bass and I’m happy.

93 decibels is just about: THIS LOUD!!! THIS LOUD!!!... (it also has an echo to it as well).
