音漏れチェック app for iPhone and iPad

Purpose

Are you worried that the sounds you or your family members or pets are making are leaking out to your neighbors or to other rooms on the upper and lower floors, causing trouble for others?
In order to prevent yourself from becoming a perpetrator of noise, you should know the upper limit of volume for each frequency (height of sound) to see how far you can raise the volume of your voice, musical instruments, TV, audio, etc.



Features

The worlds first⁉ sound leakage prevention application.

The app estimates the soundproofing performance of the room you are in based on the type of building, structure, age of the building, etc., and notifies you with a screen display and vibration when it detects sound leakage into the next room.



Details of the function

It is possible to estimate the sound insulation performance of architectural applications such as private rooms in apartment buildings, private rooms in detached houses, private rooms in offices, private rooms in hospitals, hotel rooms, and regular classrooms in schools, based on the type of building, structure, age of the building, and measured dark noise level.

The noise level and threshold (upper limit of the sound pressure level at which no sound leakage occurs) are displayed in real time for each frequency band, and when the app detects that sound is leaking into neighboring rooms or upstairs/downstairs (excluding outdoor areas), it will display a warning screen and notify you by vibration.

Precautions

This application is limited to the measurement of airborne sound (noise) and does not support floor impact sound (vibration) such as footsteps.



Background of the development of this application

The amount of time people spend at home has increased dramatically, and as a result, residents of apartment complexes are suffering from noise due to sound leaks from adjacent rooms, upper and lower floors, and voice leaks.

The main purpose of developing this application is to reduce the number of victims of noise by spreading the manners to prevent sound leakage all over the world.
