Hi I’m looking to find the maximum loudness level that Bose SoundTouch 10 can play in dB. Can you help?


I suggest you do some reading about sound measurement in decibels and if you still want to know, try asking the manufacturer.

I doubt anyone has ever bothered measuring what you are asking for as it has little meaning in the real world due to some sounds being perceived by the human ear as louder than other sounds even though they might score less on a decibel meter.

Asking for the maximum is a very big ask as there are so many variables to contend with...

How is accurate the app to measure sound decibel in android?


Number of Sound measure apps are available in Google play and iTunes which are used to measure the level of sound. But these apps do not give the accurate result all the time. The reason behind the accuracy is that many apps uses the microphone of the mobile phones which have the limit of 80-90 db. and unable to measure the value which is greater than 90-100.

dB Meter is free app which provides professional-quality measurement results, calibrated using an actual Nor140 high-precision sound level meter. With dB Meter, you can measure ambient noise levels, save your measurements and their locations, and share your measurements with others.

dB Meter couples utility with stylish design and a polished user experience: a powerful tool in a sleek package, and at a tiny fraction of the cost of professional sound meters.

What is signal to noise ratio


The noise is that produced by the working circuits of the item in question. If this is too high the signal (what you want to listen too) will become overwhelmed by noise (generally in the form of hiss). Therefore the higher the signal and the lower the noise the better. This is expressed in a ratio between the two.

Fridge water sound


This kind of noises produced gas in cooling system.
In the old coolers never heard sounds like streaming water because the compressors were very loud due to high pressures (12 bars or more), which were required for efficient cooling. Today we use more ecological gases which work (from 5 to 6 bars) at much lower pressures, thus compressors produce much less noises and now suddenly we hear sounds that never before heard. Generally speaking noises is lower, measured in decibels.

Static Noise


Is it a hissing noise or a distorted crackling noise? If it's a hissing noise then it's due to a bug in Windows that adds 30 dB of gain. It's easy to work around, though: Go into Recording devices, Properties button, Levels tab, right click on the level number so that it shows in decibels, and then adjust the level to 0 dB. It's supposed to be at 0 dB but Windows 7 defaults it to 30 dB for no reason. This isn't a problem on Windows XP or OS X.

Why do the volume numbers on old receivers start


This type of calibartion is known as a logarithmic scale.
The numbers refer to decibels below the maximum output of the amplifier section of the reciever, or decibels of attenuation (making smaller/quieter).

Without going through logarithim theorey, the logarithim (base 10) of 1 is 0. So if 1 is the maximum output of the amp, as you turn the knob down from maximum you are adding more and more attentuation to the output (relative to maximum) and so the loudness of what you hear goes down, even though the number on the scale is going up !

Most peolpe associate decibels with sound levels, but anything can be measured in decibels, so long as there is soemthing to reference it against.

Leaf Blowers Features


* CFM (cubic feet per minute) is the measure of vacuuming power. Ratings fall in the 350 to 600 CFM range. * MPH (miles per hour) measures blowing. Leaf blowers perform at levels from 125 - 210 mph. * Decibels (dB) is the noise rating. * Reduction ratio on mulching blower/vacuums calculates how many units of leaves the mulcher can produce. A 10:1 ratio means that 10 bags of leaves can be reduced to 1 bag of mulch. * Speed settings allow better control when blowing or vacuuming. * Attachments, such as extension tubes for cleaning gutters, are available separately.
