Noise Patrol App 对比 NoiseLab 的使用情况和统计数据

NoiseLab is a professional noise meter APP developed by ZKXY (member of BSWA Group). It turns your iOS device into a professional acoustical analysis meter, precisely measures the sound pressure level and the frequency characteristic around you. For acoustic engineers to comply with IEC and ASTM standards, it is essential to use external soundcard and 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. 3 profiles results can be shown 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. - Calculate and show the Current and integral Octave analysis results - Octave result can be saved, and max 3 previous Octave results can be shown to compare.
