Mosquitone Detector

icon_mtd

"Mosquitone Detector" is a new sound measurement app that detects high-frequency noises and ultrasonic sounds hard to hear for human ears. It may have been exposed to artificial high-frequency noise while you do not notice. This app can detect and visualize such high-frequency noises.

In general, the human audible range is said to be 20 Hz to 20 kHz, but very high frequency sounds above 10kHz will gradually become difficult to hear with age. For example, there are increasing cases where high-frequency high-power noise generators are installed in various places as a purpose of repelling young people and beast pests using very high-frequency mosquito noises that can not be heard by general adults.

Especially for young children, there are cases that they stay in the bad place even though on a very uncomfortable noise environment because adults can not recognize at all. Please use this app to find high-frequency noise, so it will help you to quickly get away from the bad spot or remove the noise source.

High Frequency Sound

In general, the high-frequency sound is a sound over 10kHz. By depending on its frequency component and sound level, it is different the degree of influence on the human body and the noise sensation.

As become more high frequency, the sensitivity of the hearing will be lower. When it exceeds 16 kHz, it becomes almost impossible to recognize it in adults. Despite the fact that high frequency noise has various physical influences, many people can not be aware of it, so the noise environment is ignored and unchanged.

Actually, there are increasing cases where high-frequency high-power noise generators are installed in various places as a purpose of repelling young people and beast pests using very high-frequency mosquito noises that can not be heard by general adults.

Efficacy such as repelling pests by high frequency sound has no scientific basis and very high sound level of high frequency noise may have a bad influence on human's sense of hearing. In addition, on the young children with sufficient listening ability for high frequencies, the noise environment will be in a harsh stress sound condtion.

This app is a new sound measurement tool for detecting such high frequency sound, it is possible to detect the peak frequency of a high-power high-frequency sound noise and display it graphically. For sound level measurement of high-frequency sound, the reference value (0dB) is based on our app "Sound Level Analyzer".

Important initial settings (iOS permissions)

In order for this app to work properly, it is necessary to make the following initial settings related to the iOS system.


Microphone access permission setting

At the initial startup after installing the app, the iOS system asks for permission to access the built-in microphone. In this case, you need to enable access to "Microphone".

If you have not enabled this setting, this app can not work by privacy restrictions of the iOS system. Please enable the access permission on the iOS setting, "Settings > Privacy > Microphone".


mic_access

Photos access permission setting

When the first time you save an image data with Snapshot, the iOS system asks for permission to access the "Photos" library. In this case, you need to enable access to "Photos".

If you have not enabled this setting, this app can not work by privacy restrictions of the iOS system. Please enable the access permission on the iOS setting, "Settings > Privacy > Photos".

Basic Operation

For the first boot of this app, Information screen is displayed. Please read the operation procedure before using. Tap CLOSE button to return to the top screen.
Select either ultra-high frequency ("16kHz-23kHz") or high frequency ("8kHz-15kHz") as the frequency band you want to detect.
This app has two operation modes, "Detection mode" and "Search mode". Select one of the modes and tap START button to start the measurement.

Detection mode (Detect) : It can check if there are high-frequencies and ultrasonic sounds that you can not hear.

Search mode (Search) : It can find the direction of high-frequency sound source. It can only be used when it has found a high frequency sound in "Detection Mode". The mode can be switched by MODE button.

mtd_detect

Detection mode

On Detection mode, it finds an inaudible high frequency and ultrasonic sound in the frequency band more than 16 kHz (or less than 16 kHz).

Tap Start button and it starts the detection function. If high-frequency or ultrasonic sound exist, it will be displayed on the graph as the peak frequency.


mtd_detect mtd_detect_2

Search mode

On Search mode, it finds the direction of occurrence of the high-frequency sound source that detected the peak frequency. “Search mode” can be used only when high-frequency or ultrasonic sound is founded in “Detection mode".

Please make sure to hold the bottom built-in microphone of iPhone so that it faces outward. If you measure with the microphone facing inward, microphone sensitivity will deteriorate and accurate measurement will not be possible.

Tap Start button, and firmly hold the iPhone terminal, please turn slowly clockwise. Recommended that the time required for a rotation is about 15 seconds and the rotation speed in the graph is approximately 4 rpm.

The measurement is completed by one revolution, and the signal strength of the peak frequency is displayed on the pie chart. You can find approximate direction of the high-frequency sound source relative to your standing position.

Snapshot

Tap SNAP button, you can save the current measurement display as “Photos” as an image file. The measurement time stamp is also displayed in the image.

Tap INFO button, it displays the operating procedure, support link and product information. Tap CLOSE button to return to the previous screen. If you tap "Support & Information " button, Safari starts and you can see our support page.

Release Information

"Mosquitone Detector" version 2.0 was released on February 1, 2020. UTC
"Mosquitone Detector" version 1.1 was released on August 6, 2018. UTC
"Mosquitone Detector" version 1.0 was released on October 5, 2017. UTC

Note

If the frequency changes periodically or randomly, it is not possible to determine the direction of occurrence in “Search mode”.
In "Detection mode" and frequency band "8kHz-15kHz", if the peak frequency is detected between 15kHz and 16kHz, the measured value will be displayed but the peak bar will not be displayed.
Ultrasonic measurement depends on the sensitivity characteristics of the built-in microphone, so the measurement result may vary.
Due to individual differences in iPhone hardware, the measurement result may vary.

Remarks

It is still under study about health effects on human body by listening to high-frequencies including ultrasonic sound. If the high-frequency noise of high-level is detected daily, we recommend that you consult an expert.
