NoiseLevel is a fun way to measure the sounds in your surroundings. Measure the sound level of the music you listen to, your kids playing or your office environment. NoiseLevel uses your iPhone's built-in microphone to first pick up sound and then displays it in dB (= decibels) on a status bar at the bottom of NoiseLevel's main screen. Sounds are also displayed visually as a balloon whose size and color change according to the level of the sound measured. See the balloon burst at high sound levels - you can also make it burst by creating a sharp, high sound, for an example by clapping your hands. Have fun experimenting! For best results, turn the iPhone so the microphone is pointing directly at the sound source. The screen flips accordingly. Disclaimer: NoiseLevel is fairly accurate but it should NOT be considered a professional sound level meter. The built-in microphone of the iPhone can only measure values between 35 to 110 dB and values may vary slightly between iPhones. ## Key features - Measures sound in decibels (dB) - Visualizes sound with a dynamic balloon - Balloon size and color change with sound level - Balloon bursts at high sound levels - Uses device microphone - Screen orientation flips ## Recent user reviews (10 of 25) All indexed reviews: https://appshunter.io/ios/app/noiselevel/id302830630/reviews.md ### 5/5 — Love this app *2013-09-18* I use this app in my classroom and it works perfectly for me. It gives the kids great feedback on their talking level an helps me assess the sound level in a more objective way. Money well spent. ### 3/5 — Okay *2013-07-09* Macht was sie soll und das gut. ### 5/5 — Simple app that worked for me! *2012-12-01* Not a fancy app, but was just what was needed to teach my small group of students about regulating their noise level. I have recommended to several parents and colleagues! ### 3/5 — Cc *2011-09-30* Eigentlich voll cool, aber des Mikro is halt a weng empfindlich... ### 5/5 — Super Sache! *2011-09-06* Die App macht genau was sie soll - nähmlich Lautstärker messen! Und mit 0,79 EUR finde ich sie nicht zu teuer! Vielen Dank an die Entwickler! ### 1/5 — Mit Messen hat das nichts zu tun. *2011-05-13* Ein Spielzeug, mehr nicht. Habe mal verglichen mit meinem Schallpegelmessgerät, der Messfehler ist wirklich frappierend. ### 5/5 — 使える! *2011-05-03* 小学校教員です。三年生にこれを向けて劇の台詞を練習させると効果倍増!　風船を割ろうと必死で声を出します。数ある音量計測アプリで、単純で視覚的に楽しい! ### 4/5 — Genial *2011-02-17* ...endlich schnabbelt meine Freundin in Zimmerlautstärke :D ein Traum! ### 3/5 — bei 100DB ist schluss / end by 100DB *2011-01-05* lustiges Spielzeug, wobei ich an der Genauigkeit zweifel hab. Bei 100DB ist schluss... mehr kann die App nicht! funny toy, but i have a doubt if the numbers are correct. and no more than 100DB possible. ### 5/5 — хорошая утилита *2010-11-10* прикольная софтина, жалко что уровень шума от 40 дб только можно мерять ## Frequently asked questions about NoiseLevel ### What is NoiseLevel?
