icon-rt_v100.png

"Reverb Time Analyzer" has been updated to version 2.0 now!

"Reverb Time Analyzer" is an acoustic analysis tool that allows you to measure the reverberation time of a room.

Would you like to control the sound reverberation in your listening room? Knowing the reverberation time is one of the guidelines for creating a comfortable sound space. For example, it can be obtained as objective data on the current status of various acoustic disturbances, such as high room reverberation and poor intelligibility, too much flutter echo and howling.

This app can analyze the reverberation time using the interrupted noise method, in which a random test noise signal is generated from the iPhone's speaker and then turned off. Up to 6 consecutive measurements, reverberation time analysis, and spectrogram analysis can be performed.

* Sound Level Statistical Analysis (histogram, time rate noise level)
slapro_sa_hist_v700.jpg slapro_sa_ln_v700.jpg

* Examples of sound sources and noise levels
 130 dB: Engine sound of Airplane
 110 dB: Horn of Car
 100 dB: Noise of passing train
 90 dB: In loud factory
 80 dB: In the train, Vacuum cleaner
 70 dB: Noisy office, Noisy street
 60 dB: Quiet Car, Normal conversation
 50 dB: Quiet office
 40 dB: In the library, Quiet residential area
 30 dB: Outskirts of midnight, Whisper
 20 dB: Sounds of rubbing leaves

Note: The standard noise measurement range is 30-130 dBA, and the measured value (Leq) is about 30 dBA in a quiet room of the household. Due to the presence of background noise, noise levels are never measured at 0dBA even in very quiet environments. In a typical anechoic room, the noise level is around 5-15 dBA.

The World Health Organization (WHO) has published noise level indicators related to health risks caused by noise, which are listed below as a reference for noise management.

* Noise level and permissible exposure time
 100dB: only a few minutes/day (weekly limit of 20 minutes)
 95 dB: 10 minutes/day (weekly limit 1 hour 15 minutes)
 90 dB: 30 minutes/day (weekly limit 4 hours)
 85 dB: 1 hour 45 minutes/day (weekly limit 12.5 hours)
 80 dB: 5.5 hours/day (weekly limit 40 hours)

In general, the quality of life begins to be affected at levels above 60 dB, and the risk of health problems increases at levels above 80 dB. Prolonged exposure to high levels of noise can cause temporary hearing loss.

icon-lfd_v700.png

"Low Frequency Detector" has been updated to version 7.0 today!

"Low Frequency Detector" is a sound measurement application for detecting inaudible low frequency sounds.

Low frequency sounds lurk everywhere in our daily lives. Unlike noise, low frequency sounds are often hard to notice and have a variety of physical effects. While you may get used to it if it is a common noise, infrasound is more likely to get worse over time.
For example, if you have insomnia or poor physical condition, it may be caused by infrasound. Please use this application to find out the presence or absence of infrasound and its source, and use it as a noise countermeasure.

This application can measure and display the power level, time course, and frequency analysis (1/3 octave band analysis and FFT analysis) of infrasound.

- Time course
