NIOSH Sound Level Meter

Incredibly powerful yet extremely simple tool. It measures the Sound Pressure Level and also gives some statistics and weighted levels. Very detailed. It has been exposed to known sound fields and it matches very well the reference equipment (tested on iPhone 8 with built in mic, no calibration applied). I recall it very consistent with the measurements across devices. Great work from NIOSH

Por qué no se puede usar con el dispositivo bloqueado? Es un incordio tener todo el rato la pantalla encendida para medir las dosis.

Desde el micrófono del móvil mide en una habitación en silencio una media de 30 dB, al respirar con normalidad (sonido casi imperceptible) a 1m fluctúa ligeramente aumentando hasta 35 dB, me parece poco realista que una persona en una habitación en silencio este cerca del límite permisible.

Muy fiable!! Buen trabajo!!

Medir el nivel sonoro, al menos de forma aproximada, puede ser muy útil (por ejemplo, en casa, cuando quieres demostrar a alguien que tiene el volumen de la tele muy alto). Esta herramienta sencilla, funcional y gratuita es una app merecedora de las 5 estrellas.

- -:- - keeps popping up. Had to delete the app. Will try to download it again later and see how it works…. Update: Creator contacted me and informed me how to fix the issue. Easy to do. Now, if I have any issues, I know what to do. 5 Stars

very useful, seems accurate, easy to use, two problems/recommendations; when i’m recording a measurement and leave the app, even after pausing it, when i come back to NOISH that measurement is wiped. additionally it would be very helpful to be able to use all the apps on my phone during a measurement especially say, spotify because i am trying to gauge whether i am listening to music at a healthy volume but if i want to do that i have to play the music from my ipad while i measure with my phone which is a hassle.

App will not report dose or TWA; using an iPhone 14 Pro.

The data is easy to collect, but I am a retired 85-year-old certified safety, professional, and not familiar with the current definitions above and beyond the basic noise level. I would like to enter this information into my Apple Health app.

It takes very accurate sound measurements, but from time to time the app will stop displaying the current db reading and show a blank - -.- reading. I hope this can be fixed in the next update. Otherwise a very useful app.
