New updated iOS App - "Low Frequency Detector" ver 5.0


"Low Frequency Detector" has been updated to version 5.0 now!

"Low Frequency Detector" is a new acoustic measurement tool for detecting the low frequency sounds that is hard to hear in the normal situation.

It also allows you to examine the frequency component of the low frequency sounds by 1/3 octave band analysis and FFT analysis.

In general, the low frequency sound is a sound wave with 1 Hz to 100 Hz. By depending on its frequency component and sound level, it is different the degree of influence on the human body and the noise sensation.

The human ear is insensitive enough to become a low frequency. If you may be exposed to the noise of neighboring constructions and factories without noticing, you may have a feeling bad and a sense of oppression. In this case, you can check what type of low frequency sound exists by simple operation of this app.

Please use this app to find out whether or not low frequency sounds are present and their sources, and use it for noise control.

# Time transition graph

# 1/3 octave band analysis

# FFT analysis

After the completion of the measurement, you can display the report of peak LF Level analysis.

# Report of low frequency sound analysis results

# Example report for RED status (Hazardous Noise Levels).

The following are some of the sources of the low frequency sounds.

# Sources in the home: heat pump water heaters, household fuel cells, ventilation fans, refrigerators, air conditioners, blowers, dehydration pumps, etc.

# Outdoor sources: cars, trains, airplanes, outdoor air conditioning units in buildings, factory noise, long-term vibration of road bridges, wind power generation, etc.

If you have unexplained health problems or feel unwell, you may be exposed to such low frequency sounds.

Detailed information about this app is available on the AppStore and can be found at the following link.
