Software Listing: Automatic Sound Level

This project is for matlab development of a virtual sound level meter. The program will read in a .wav file and allow the user to analyze it as one would analyze a sound field with a sound level meter..

  • Platform: WinOther

This tutorial/demo presents the design of a sound level meter in Matlab. The Data Acquisition Toolbox is used to implement a real-time spectrum analyzer. The decibel meter is implemented in the frequency domain using Parseval's relation. Documentation is provided in the included PDF. Further information is available at: http://mesh.brown.edu/dlanman..

The Portable Sound Monitor (PSM) is ideal for anyone working within the music industry ( our primary market ) as well as environments where it is imperative to measure the quality of sound, such as motor racing, shooting events and public displays. The main advantage PSM is the ability to be able to forward the recording via email as well as text message. The quality of the recording is somewhat dependant on the ability of the Smartphone microphone. Generally speaking the handsets on the market that make use of Windows based technology tend to be the high end units and therefore tend to also come with a well built microphone.

Sleepy Sound has been designed according to medical recommendations and promotes more deep relaxation before and after sleeping. Try Sleepy Sound after hard working day. Turn on your favorite quiet music from CD or player on computer and launch Sleepy Sound. It will decrease sound level step by step and you relax after him and fall asleep. Then after desired time period Sleepy Sound will increase step-by-step sound level and you softy awake from sleep. Time period before sleeping, amount of sound levels and wake up period choose according your biological rhythms..

Sound Level Meter is in the 4th set of the Smart Tools collection (noise).

SPL(sound pressure level) meter app uses your phone mic to measure noise volume in decibels(db), and shows a reference.

REMEMBER!! The smart phone microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are LIMITED by the manufacturers and the very loud sound(100+ db) cannot be recognized. Moto Droid(max.100), Galaxy S3(81dB), Galaxy Note(91dB), Galaxy S2(98dB)...

See the 4-5nd pictures. I had calibrated many android devices with the actual sound level meter with dB(A). So you can trust it in routine-noise levels(40-70dB).

  • Platform: Android, WinMobile

Best Sound Meter (sound pressure level) is an app which can measure the actual sound level meter with dB.
It uses your built-in microphone and shows a reference. We had calibrated many android devices with the actual sound level meter with dB.

You have to know that the built-in microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are limited by the hardware limitation, and very loud sound (100+ db) cannot be recognized.

Remember that it's only a device for fun and please use it as an auxiliary tool.

The Sound Meter uses the microphone of your phone / tablet to measure the sound level, and display the result on any of the following Sony Smart Accessories:

* SmartWatch 2
* SmartWatch
* Wireless Headset Pro

Besides the actual sound level, the maximal and the average sound levels are displayed at any time.


Disclaimer: the results may be different than what a professional Sound Meter device would measure.

The TopoGX application was designed to be a high quality software application which can intelligently convert a 2D DXF drawing into a useful 3D DXF drawing. It is intended for surveyor produced drawings like the one to the right here (click the image for more details), but is equally suited to any 2D drawing where the Z levels are represented as text items.

Additionally TopoGX contains a powerful triangulation engine which can produce a constrained delaunay triangulation (viewable surface) of a 3D drawing almost instantaneously.

Here are some key features of "TopoGX":

Automatic 2D to 3D DXF Conversion:
* Single button conversion - total automation
* Numeric text items are converted to Z levels.

Train your dog to do tricks!
Train your dog to stop barking!
or if there is a dog next door, use this app to make it silent.

Features
-Variable frequency tone generator
-Bark detector
-Sound level meter

How does it work?
Dogs are capable of hearing sounds at much higher frequencies than people. A dog whistle works by emitting a high frequency tone in a range that a dog does not ordinarily encounter a* * typically between 14,000 Hz and 20,000 Hz. The highest frequency a normal middle aged human can hear is 12,000-14,000 Hz, so dona* t be alarmed if you cana* t hear the dog whistle yourself.
