- Sound levels are measured on a scale known as the decibel (dB) scale. The higher the number the greater is the sound level. Too much noise can damage hearing. Exposure to 90 decibel sound levels for a long time can cause permanent hearing loss.

Jun 19, 2024 · Today, I’m going to walk you through everything you need to know about loudness, from explaining decibels and sound pressure levels to the warning signs a concert is getting too loud. So if you're an avid gig-goer, you'll want to read on.

Sound levels are expressed in decibels. Sound levels for common sounds cover a range of about 130 dB. (See chart below for sound levels for common sounds). A quick look at the chart reveals that sound level is very a different thing than sound intensity.
Nov 30, 2006 · 'Level' is a term with a precise meaning. For a real sound traveling in air (or any other medium), its level is measured in terms of sound pressure. Sound pressure is the difference from normal air pressure caused by the sound. Difficult bit coming ---Sound pressure is measured in newtons per square meter.
Feb 5, 2024 · In our everyday lives, loudness is more than just a measure of sound intensity; it’s an intricate perception shaped by physical, psychological, and environmental factors. In this article, we explore how decibels interact with the human auditory system to create the sensation of loudness.
- Rule #1: +3dB = 2X The Amplifier Power; +10Db = 10X Theamplifier Power
- Rule #2: +6Db = Double The Sound Pressure, 2X Driverexcursion

Going from 1 watt to 2 watts of amplifier power gains 3dBof additional output; that's a pretty good deal right? Again, going from 2watts of amplifier power to 4 watts gains an additional 3dB of output. Giventhe relatively low cost of amplifier power these days, buying a more powerfulamplifier is a no-brainer. So now that we have a basic understandi...
This statement has a lot ofimportant implications. Certainly the notion that 6dB of extra output requiresdouble the driver excursion (all else being equal for sealed systems; venteddesigns are a bit harder to generalize about) should give some appreciation forwhat it takes to achieve higher output levels. For example, if you have a pair ofsubwoofer...
By now, your head may be spinning with numbers, and it’stime to bring it all home: It’s great that 10 times the amplifier power canpotentially yield an additional 10dB of output, but what does all this mean toyou, the listener? The answer is that itdepends: our ears are complicated mechanisms whose sensitivity varies withfrequency, and it is import...

For the majority of audio professionals, it is most important to understand decibels as they relate to electrical power (dBm and dBW), electrical voltage (dBV and dBu), analog and digital audio meters (dBVU and dBFS), and sound pressure level (dB SPL).
