yes very loud!!
babies can be really loud and I'm not kidding
It is so loud, sometimes it can break the membrain in your ear and make them bleed.
* Why do people jump when they hear loud voices? It is because they are frightened

About as loud as a shop vac
I think it's $75 per year, but not positive.
dBA stands for A-weighted decibels, a unit used to measure the loudness of sound. It adjusts the measurement to account for the sensitivity of the human ear to different frequencies, providing a more accurate representation of how loud a sound is perceived by humans.

I had to do a DBA with a teacher.
DBA - airline - ended in 2008.
DBA - airline - was created in 1992.
51dba is almost 3 times quieter than 59 dba.
A sound at 55 dBA is louder than a sound at 51 dBA. Each increase of 3 dBA represents a doubling in sound intensity, so a 4 dBA difference is noticeable.
There are many companies that provide DBA services such as DB Specialists, Percona, Savvis, Enterprise DB, Lumin21, DBA Direct, Triniti, Blue Crystal and DBA-24x7.
The most general way to describe it is that amplitude is related to how loud or soft the sound is. Greater amplitude causes a louder sound. Frequency, how rapidly the waves come per second, is related to the pitch of the sound. The greater the frequency the higher the pitch. Amplitude is how high and low the waves appear to be when they are graphed. Frequency is the measurement between peaks of waves of a graphed sound. It is easiest to learn and understand these differences when you look at pure sine waves of sound, sound with no harmonics or overtones. The sounds you hear in the real world are more complicated than that, but the basic principles of amplitude and frequency still apply.
not over 75 b/c it will get to loud
