【實用生產應用app】SoundMeter.Pro|最夯免費app-綠色工廠好玩App

Based on SoundMeter, the original sound level meter app for iOS, SoundMeter Pro turns your iOS device into a handheld data-logging sound level meter (SLM), data-logging noise dosimeter, and real-time analyzer (RTA).SoundMeter Pro supports exponential-time-weighted sound level (Lp), equivalent sound level (Leq), and percentile-exceeded sound level (Lx) measurements in whole and 1/3-octave frequency bands with various time and frequency weightings. Overall levels can be logged at intervals as small as 0.1 seconds for durations of up to two weeks (larger intervals are required for greater durations). The built-in signal generator tool can be used for generating calibration test tones, noise, chirps, or other periodic signals. SoundMeter Pro’s data-logging Noise Dosimeter tool calculates and logs noise dose, projected dose, 8-hour time weighted average (TWA), and A-weighted sound levels.FEATURES- Apple Watch app for remote monitoring and control from your wrist.- Measure time-weighted, equivalent and percentile-exceeded sound levels.- Employ Flat, A, or C frequency weighting.- Time-weighted measurement options include Fast, Slow, and Impulse weightings.- Keep track of peak and maximum sound levels.- Export data from each of the three tools to CSV, MAT, or TXT files.- Save high-resolution sound level display images to PDF files or to the device’s Camera Roll photo album. Descriptive text may be added to the image before it is saved.- SoundMeter Pro’s SLM and dosimeter also offer data sharing via photos, email and Twitter.- Calibration controls enable automatic sensitivity calibration, relative to a calibrated sound level meter, or manual entry of the microphone sensitivity.- SoundMeter Pro supports screen rotation to any orientation.- Data acquisition support includes an http server for downloading PDF, CSV, TXT and MAT files via a standard web browser running on a computer connected to the same network.SoundMeter Pro includes all the functionality of SoundMeter with all its available in-app purchase upgrades.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.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.For iPhone/iPad/iPod touch audio I/O compatibility and frequency response measurements, visit http://blog.FaberAcoustical.com.NOTE: SoundMeter Pro has been designed to meet or exceed ANSI or IEC standards for sound level meters. However, these standards require conformance of the entire measurement system, including hardware, software, and microphones. Contact a certified acoustical testing laboratory for information regarding meter standards qualification.
