NoiseLab is a professional noise meter APP developed by ZKXY (member of BSWA Group). It turns your iOS device into a professional sound level meter (SLM), precisely measures the sound pressure level around you. For acoustic engineers to comply with IEC and ASTM standards, it is essential to use external microphones. MicW i437 microphone is recommended to use in high-precision measurement, and i437 can be purchased in Amazon and other web-shops online. HIGHLIGHTS: - Support the built-in Microphone and the external microphone, the latter has 3 gains to choose. - Measurements of any combinations of Filter Z, A, B, C and Time detector Fast, Slow and Impulse simultaneously. - The system can be calibrated by using sound calibrators with 94 dB and 114 dB at 1000 Hz, or manual input of calibration factor. - Measured time history of sound pressure level can be saved into the list of history report and easily export to computer and send by email. About BSWA Group: Established in 1998, BSWA Group has twenty years of experiences in developing and manufacturing acoustical measurement instruments. BSWA’s products are distributed in over 40 countries through sales partners, covering the businesses of: - Manufacturing the world class measurement microphones - Developing acoustic measurement systems and devices - Designing and building anechoic chambers - Acoustical consulting for environmental and noise control projects.
