Decibel X:dB Sound Level Meter App Reviews

Very precise.

Great user experience. Highly professional interface and very responsive measurements.The logging feature is a great bonus.

It works without any problem.

This seems to tell me that things are noisy when they are not, but does not tell me anything when I hear noises with my own ears, like the loud popping or the bangs I hear around my home

A simple task but well executed!! Great new features and still maintained the ease of use.

Very useful and sensitive.

Dont know how accurate it is, but its pretty handy

Good for checking street noise levels when looking for residential houses.

I wont be buying the paid version as the lite version doesnt really do much. Companies have to change their way of marketing. Giving me something so limited doesnt really help me want the paid version anymore. Sorry, too little to make it worth buying!

It is handy for checking noise levels anywhere.

簡単に使えます

Good app absolutely ruined by full screen pop-up ad with auto-play audio. Infuriating to use. Deleted.

Effects are powurful. Very sensitive. You can send the sound level graph data by e mail. Besides that it is Free. I love it.

It is good enough, thank you.

Easy to use and it work properly

Its amazing that this app on your iPhone can be so useful to measure sound noise on industrial site as well. Recomend!

Very Nice app - I use when I want to check the place while searching for the location for the New house

It was useful during my science& and physics experiment

Works fine, quickly, without blocking, I would recommend it. Noise/volume-Letters could be bigger as they are most important. Sometimes ads appear loud and full screen.

Pros: - dB graph can be sent via email for futher analysis, non of the free apps of this kind have this feature; - The text label describing the environment is unexpectedly correct! "Quiet home" is at home, and "avg metro" is in the metro!:) Cons: - Not sure about the absolute calibration, no slow/fast switch; - readings jitter even in stable conditions, a value of 4 dB is recorded in a log file once every second (must be some calculation bug) - Sometimes readings do not restart, when app goes from background to foreground; - When a headset is plugged and unplugged, readings go up by 20 db and stay there. - Resetting maximum should be one tap without confirmation.
