"How Loud Is It" provides a simple, fun way to measure audio volumes in your environment. The app shows the approximate dB (decibel) level, also known as Sound Pressure Level (SPL). This particular audio meter sports an analog display, which is designed to more closely resemble commercial decibel meters. This app is intended for personal and entertainment use only, not for professional dB/SPL measurements, for which you should buy a real sound meter from your local electronics store. The app provides relative, approximate values ...

Pocket RTA is a highly portable award winning real-time spectrum sound analyzer for the iPad. Pocket RTA has many advanced features which are normally only found in much more expensive sound analysis software, providing fast and accurate spectrum analysis suitable for both amateur hi-fi enthusiasts and professional A/V engineers. Uses include system calibration, monitoring of noise levels and testing of audio equipment. PocketRTA samples sounds using either internal or external microphones and then applies a Fourier Transform to ...

8ve (octave) oscillator Lite gives easy access to a variety of test tones for quick hearing testing, room acoustic testing and equipment testing, but with limited possibilities. The frequency of the test tomes can be changed in octave steps and the output level can be varied in decibel steps but to a lesser extent than is possible in the full version (8ve oscillator). Octave oscillator Lite produces the same test waveforms as the full version (sine, pulse, square, sawtooth and triangular as well as noise) at fundamental frequencie...

The sound is loud, but is it really loud? What is "loud"? How to judge the intensity of a sound? Here's the solution: iNoise Meter. How does it work? This noise meter uses the microphone built into your iPhone to determine the intensity of the sounds it captures. Then displays it in dB SPL (Decibel Sound Pressure Level) directly on your screen. !!! Wherever you go, you can test the loudness!!! OPERATIONS: Very simply, just start noise meter and see on the screen the intensity of its surroundings. FEATURES: - Easy to use, lit...
