The app can detect high-frequency sounds (from 8 kHz to 23 kHz) using the iPhone's built-in microphone. In order for this app to work properly, it is necessary to make the microphone access permission settings related to the iOS system. If it is enabled, but it is not working properly, the built-in microphone may be damaged in some way.
Great little app
Terrible app

Funktioniert nicht!
No instructions or way to test.

Please refer to our support page for this app. You will find reference information on environmental standards for high-frequency noise.
シンプルで使いやすい
コスパも適当と判断します。
残念な点は、測定できる上限が22kHz程度までで目的としていた測定が半分ほどしかできなかったことです。ハード的な限界だったのかもしれませんが、星一つ減らして星四つとさせていただきました。
Works very well.

Prima ...
es funktioniert.
andere möglichkeiten zum nachweis von ultraschall waren z. t. erheblich teurer als diese app.
