This decibel meter app is extremely easy to use. I use it to measure the sound machines that I sleep with to make sure they are not too loud for the extended night time hours. I use it almost nightly to check because the sound machines can change volume very easily. Also used it to protect my granddaughter’s ears at night from her noise machine.
