Comments on Decibel X PRO: Sound Meter for Android

★★★★★ Neil Young · Oct 12, 2021

Love this app. It's a Godsend when neighbors say I was noisy, but I can prove otherwise with Decibel X.

★★★★★ Jan Schoen · Jun 16, 2021

Thanks to this app I can do my voice exercises and gauge my improvement. Was losing my voice due to Parkinson's disease. My voice therapy specialist checked its accuracy and said it is good. I'm definitely satisfied.

★★★★★ Jai Cabryizky · Jul 15, 2022

Very useful, versatile, and informative app. I bought the pro Version of this app so that I could measure the noise output on my welder and the water cooler for my TIG torch, which were fairly noisy. My intent was to shave off as many decibels as possible without compromising performance in order to avoid pissing off my neighbors. This app helped me shave off a solid 12 decibels, a noticeable difference! Thanks

Who needs a Unix Epoch time stamp and Leq in every line of CSV file? They call this a professional software, but any professional knows how to calculate Leq from the sound levels and time intervals. Calibration top fine tune is not responsive, bottom bar jumps with no fine tune option. No L (90), L (10) or L (50), which are important. The audio does not synchronize well with the histogram. No options to choose where I want to save files.

★☆☆☆☆ Julian Charnock · Jan 25, 2024

Disappointing. Looks so good and useful but the dosimeter and recording locks up after a few minutes :(I paid a single fee of £25 for the pro version of this software: not a subscription. I was hoping the premium features would work.

★★☆☆☆ Johan Mårtensson · Nov 16, 2023

Saving camera photo with sound readings is not possible. Nothing happens when you push "Save to Gallery" after taking a photo with the app. It is able to save video though, but that also means saving a lot of pointless video data even for just a 10s sound measurement. Using Samsung S22

★☆☆☆☆ David Frost · Jun 21, 2021

Was perfect until latest update ruined it. Free version still works fine. Suggest stick with free version.
