Decibel meter
Just put this app on my phone as I was curious about how loud my dogs bark was, turns out it is very loud, I am now looking forward to seeing how loud other things are like my TV and haha the wife’s snoring, but I won’t tell her it’s just for my info,
異様に大きく出る
深夜、感覚的には無音状態なのに常時43dbってことはないでしょ？ 他のアプリより20db位大きく出る。信頼できない。
Decibel Metre meets Aviator December2024
Lease-Purchased 2025 Aviator Lincoln for quietness and performance, thus needing a reliable evaluation of this car to discuss classical ballroom music in traffic noise. Car stays in the 20~30db range, with conversation being louder than ambient noise! Impossible to have known this without this App for cellphone.
数値が低く出る
他のアプリと比べてかなり低い数値が出る。 測定したい環境の騒音を過小評価して誤った判断にも繋がりかねないので注意が必要。
Not sure I understand!
Thanks for developing this app - I want to use it to try and understand the difference between appliances before I spend. But just having the app open logs in at 42dcb am I supposed to be able to set it somehow? Or is this the ambient noise level?! Feel I need a few basic instructions built in. Thanks.
I love it

結果が不正確でした
音がする場所と明らかにそこより静かな場所で対して結果が変わりませんでした。
Leuk
Ziet er goed uit, wel erg gevoelig.
Goed waarneembaar
Helaas niet op te slaan
補足
履歴データが保存出来るといい。 周波数解析出来るといい。
Worth
No money needed accreted and show what it sound like
精度悪過ぎ
手持ちの校正済みの騒音計より20dbも高く表示されて目安にもならない。
Simple gratuit
Fonctionne parfaitement par contre je ne connais pas si les résultats reflètent les vraies valeurs. Il faudrait comparer avec un sonomètre pro.
It’s just not accurate
I’m sorry to hit you so hard. I have two other Decibel apps. In a quiet room, they measure between 29 and 31 dB. This app in the same room measures 20 dB. Everyone else seems to be OK with it. Maybe it’s just me.
Reset bug
Nice UI, and simple to use. Sadly, the reset button does not reset the average value, so if your previous measurements were of a loud sound, then the average will show a high value even in a quiet place. Also, no calibration feature, so not possible to align multiple devices.
Helpful tool
What a great tool. Helps with stereo listening. With my speakers
こりゃだーみだ
部屋にいるが30m先で大型機械でコンクリートハツリしてるけど33dbしかない。 うるさくてうるさくて
分かりやすい
日本語も欲しい
What is measuref
The shown average sound is lower than the minimal value. It seems that the average value is not reset with the reset button.
Simple, small and does what it says
It just works. No frills, no annoying ads (yet), doesn't consume much storage at all. I like it.
Please fix spelling
Please correct Quite Room to Quiet Room
全然数値ちがう
耳の遠い祖父のテレビがうるさくて教えたくて数値が分かれば…と思ったんですけど、テレビの音量変えても同じ数値しか出ません。 たまに40db位になるだけ。他のアプリだと65db以上あるのにコチラのアプリは20db位です。 数値も低いし、適当なのではと思う。ちなみに自宅の東芝REGZAのテレビの音量は30~位です、普通の人は20前後だと思います。
使える
無料でこのぐらいの精度なら十分満足できる
Just a tweek will make this a 5 star app
This app is excellent for the UI, it’s so simple and clear but it’s useless other than as a comparator as the displayed readings are clearly out of calibration. iPad mini reads average 20.1 dB and iPhone reads 24.7 average when both are placed next to each other. Both these readings are very much too low but no way to adjust calibration so unfortunately the app is of no real use. It’s such a pity as “the ship sank for a ‘hapeth of tar”. 5 star for UI, 5 star for simplicity, but 1 star for application.
Parâmetros máximos
Esse app tem como parametrizar um valor máximo que ao ser ultrapassado por x segundos parametrizados emite um aviso sonoro? Seria bom ter.
New reference speakers
Very good app, helpful and informative for my music!!
Odd readings
Only gave readings around 20-30dB when listening to music at 60-70dB according to another similar app which seems closer to my expectations. After opening again it gives 40-50 readings at same volume. Those are consistent readings over time. Not sure what’s going on with it.
I want save to file functions
I am recording noigy actions
日本語も書いて欲しい
英語だと読めないので日本語でも書いて欲しいです。

Zaniża pomiar
Amazing!
Easy to use, and it keeps an average for you in case you need to show it to annoying neighbors… or the police of they are called. 😂😂
Avis
Les valeurs sont fausses par rapport aux mesures faites sur d’autres applications, 30 db de différence
Wasn’t sophisticated enough for me
It’s a cute app, but only seems to give A-weighted measurements, not C-weighted which is what you need for most sound-system measurements. Also no response time settings - there should be fast and slow settings. Iya great that it appears to log SPL levels against time, but there appears to be no way to export or save those graphs or logs, nor any way to scroll back to earlier measurements that have now fallen off the left side of the chart. Also not sure how accurate it is, and no obvious way to calibrate it against a professional SPL meter. So, quite pretty, but not useful for me.
Gemiddelde AVG klopt niet
Mooie app echter het gemiddelde klopt niet. Dit moet ergens tussen min en max liggen maar nu ligt het ruim onder het minimum. Ook mis ik een calibration optie.
Brevity is the soul of wit.
Simple and effective, and not behind a paywall.

全部英語でわからない
誤差がなかなかあります。
用途はバイクマフラーの音量測定です。 認定マフラーでは無い為、目安程度に把握しておきたかったのでダウンロードしました。 使い勝手は簡単なので良いのですが誤差が結構あります。 というのも、うるさいマフラーだとは思ってましたがこんな数値高いか？と疑問に思い、測定器を別途購入し再測定した所およそ25dB位高かったです。 20dB位差があるていで思ってくれれば良いかと思われます。 ちなみにアプリだと113dBなのに、測定器だと87程でした。 参考数値までに。
Gr
Excelent applc. Best i have try
おそらくかなり不正確
いくつかのアプリで同じ環境で測定したところ、このアプリだけ大幅に値が低く出た。(他が50〜60dB程度の環境で20〜25dB) 多数決なので説得力はないかもしれないが、参考までに
Werbelridte
Werbung macht ja nichts. Überblendet diese aber den Start / Pause Button, ist das schlecht. SEHR SCHLECHT.. Warum nicht mal ohne? Dann gäbe es auch 4****! Ansonsten misst die App recht genau, immer abhängig von der Empfindlichkeit des Mikros.
Db
Simple and averages the Db rating👍
Simply doesn’t work.
Downloaded several decibel meters at the same time. Tried each one. This one is completely unresponsive, with no way to turn on microphone or off microphone, no way to register any noise whatsoever on any meter that it shows on the screen. Non-functional.I thought Apple tested these before allowing them on their app store.
