SoundMeter Basic turns your iOS device into a handheld sound level meter (SLM) and noise dosimeter.

Input signals can be acquired from the current audio input path (iOS automatically selects the audio input path according to which external audio devices, if any, are connected to your iOS device). Sensitivity calibration can also be performed for any audio input device or input channel.

In addition to real-time sound level measurements, SoundMeter can store acquired sound level data, including date, time, and location, in CSV or TXT (tab-delimited) files, MAT-files, or high-resolution PDF images for later retrieval from your device.

Features:
- Level Meter
-- Lp and Leq sound levels
-- Standard Flat, A, C frequency weighting
-- Standard Fast, Slow, Impulse time weighting
- Noise Dosimeter
-- 8-hour Noise Dose, Projected Dose, TWA calculations
-- Criterion Levels: 80, 85, 90 dB
