Faber Acoustical announces SoundMeter Pro for iOS

Lehi, Utah – Building on the success of SoundMeter, which debuted on the iPhone App Store in August of 2008, Faber Acoustical has announced the release of SoundMeter Pro. SoundMeter Pro turns your iPad, iPhone, or iPod touch into a handheld data-logging sound level meter (SLM), data-logging noise dosimeter, and real-time analyzer (RTA).

SoundMeter Pro works with built-in or external measurement microphones to deliver reliable sound level measurements, including time-weighted and equivalent sound levels in addition to percentile-exceeded sound levels and noise dose. Measured levels can be logged at intervals as small as 0.1 seconds for durations of up to two weeks (longer measurement durations may require larger logging intervals). The built-in Octave tool performs sound level measurements in whole or 1/3-octave frequency bands.

In a recent article published in the Journal of the Acoustical Society of America, NIOSH researchers found that, out of over 130 sound measurement apps for iOS, “SoundMeter is the app best suited for occupational and general purpose noise measurements.” SoundMeter Pro builds on everything SoundMeter has to offer.

With the built-in or headset microphone, SoundMeter Pro can measure peak sound levels of up to approximately 130 dB. Results may vary between iOS devices and headset microphones. External microphones may enable the measurement of much higher sound levels.

SoundMeter Pro also includes various features that users have come to expect from Faber apps, including the ability to save measurement data to CSV, TXT, or MAT files, save measurement displays to high resolution PDF files, switch between three different color schemes, and calibrate microphone input sensitivity. Exported data files may be retrieved from the iOS device via iTunes File Sharing or by enabling the app’s built-in file server and downloading the files to another device or computer via a standard web browser. The built-in signal generator tool further extends SoundMeter Pro’s utility by producing any of various test signals, including white noise, pink noise, frequency sweeps, and periodic waveforms.

Faber Acoustical has simultaneously announced the availability of SoundMeter 5.0. The new version of SoundMeter adds support for a new Data Logging Upgrade, which is available via in-app purchase. SoundMeter Pro includes all the functionality of SoundMeter 5 with all its available in-app purchase upgrades. Although both apps run on iOS 6, each also features a user interface tailored for iOS 7.

NOTE: Although it has been designed to do so, SoundMeter Pro is not guaranteed to meet ANSI or IEC standards for sound level meters. These standards require conformance of the entire measurement system, including software, hardware and microphones.

The built-in and headset microphones are suitable for certain, basic sound level measurements, but high precision external microphones may also be used with appropriate audio accessory hardware. Even though default sensitivity values are included for the built-in and headset microphones, for best results, SoundMeter Pro should be calibrated before use. Sound levels may be off by a few dB when using the default microphone sensitivity.

Device Requirements:
* iPhone, iPod touch, or iPad
