Noise Meter

The Noise meter records sounds in the vicinity of the device and calculates their levels in decibels.

The sound level depends on the distance between the sound source and the place of measurement, and varies slightly among different devices due to their microphone characteristics.

Bear in mind that it is impossible to reduce the sound pressure and sound intensity to zero, unless you go to a vacuum, because of the thermal motion of molecules.

Here are some referential ratings:
Loud noise … 80 dB
Vacuum cleaner … 70 dB
Conversation … 60 dB
Average home … 50 dB
Quiet library … 40 dB
Quiet bedroom at night … 30 dB
Sound of breathing at 1 m distance … 25 dB

Device limitation: When using the Noise meter the speaker is disabled.

This is another application in a new generation of applications which is slowly but surely transforming my BB standalone into a WORKTOOL for me, not just a depressing plaything. Inspiring!

As accurate as it can be!

It’s on a Blackberry using the microphone so I mean I wasn’t expecting the most accurate thing in the world. My house is about 55Db and when I blow into the mic it was something like 115 or 120. So I’m sure it works, it’s not just a bunch of bull- but I can’t vouch for accuracy. Definitely works if you’re just curious to compare if something is louder than something else! I know I’ll be using it!!! :)

2 bucks for a SPL meter? WOW!

It works great. Quick response time. 27db in quiet bedroom seems accurate. 110db when I blow air at the pickup like it should. It’s simple and it works and it’s cheap. Going car shopping today and wanted to measure noise levels in various cars. This should do the trick nicely

Hi, a sound level meter is very useful for me. A practical, REAL WORLD application. Bring on such things! My only criticism is: I wish you could slow it down marginally at the user end. The highly active numerical readouts are difficult to fix on, so my eye goes to the more stable graph and level meter to get a reading. Keep up the good work.

    Hello, What is the dB scale used (dBA, dBC or dB SPL)?
    Is the value indicated is for average or peak dB or do you have both?

    Hi! Thanks for your question.

    Noise meter uses dB SPL scale. It measures peak dB, average dB is under development.

    I would like to mention that device meter is not comparable to real sound level meters due to device limitations.

    The application measures 16-bit audio signal (DAV = digital audio value) and that is the only realistic value given by device that again depends on its specifications.

    We also have problems with older BlackBerries and we are inviting you and others to participate as Noise Meter testers (giving you production release of Noise Meter and Beer Buddy for BBM for free).

    Are you working on spectrum calculation in octave and third-octave bands as well similar to the iPhone apps?

      No, we are not. Devices are limited and their OS versions (5, 6, 7 and 7.1 – w/ and w/o CDMA support) are so incompatible in the area of sound recording that we are unable to enhance application under such conditions.

    Average db would be a great addition. As is stands I have used this app to tweak my home theater setup. A great $2 app! Is there any ETA on adding the average feature? Thanks.

    Also, could you explain the two other readings (% and DAV)?

    DAV is 32-bit value given by microphone0s A/D converter.
    % is value of DAV compared to the max value (32767).
