Decibel dB – Sound Level Meter 对比 Decibel: dB Sound Meter 的使用情况和统计数据

Decibel Meter is an app intended for objective, real-time measurement of ambient noise and sound levels. It is intended for noise pollution control with the aim to protect the health of its users. The app displays quantitative noise level values in decibels using various measurements both in numerical and graphical form. The app also features a fully functional noise level meter to measure the user’s noise exposure over a period of time according to NIOSH and OSHA (to be chosen by the user). FEATURES: • Measure noise level in decibels (dB); • Track minimum (MIN), average (AVG) and maximum (MAX) sound levels; • Record measurement results; • Save, export and play recorded measurements; • Photos and videos with the ambient noise level overlay; • Noise level meter compliant with NIOSH and OSHA. The app was created with the purpose to prevent negative noise effects on the health of its users.

With dB Sound Meter, you can measure ambient noise levels, save your measurements and their locations, and share your measurements with others. Get noise data more comprehensively and more accurately: ●Minimal, average and maximal decibel ●Real-time decibel in dial and graph ●Levels of noise ●Calibrate before use for precise data ●Review measurement histories ● Noise dosimeter will help you understand how noisy it is at home and at your workplace. ● Highly accurate measurements. Customize your sound meter ●Save audio file while measuring ●Set decibel warning when the value is higher than the preset one ●Open the sound or vibrate for the warning ●Apply the black or white theme Other features of sound meter: ●Re-start measuring ●Suspend recording ●Rename, share and replay the recording ●Indicate the measuring duration, time and status Notice: 1.To get an accurate decibel of sound with this decibel meter (noise meter), please calibrate before use (because the performance of the microphone will be different for each device). 2.Adjust the decibel according to your experience or calibrate with a real sound meter device for comparison. (Because we couldn't estimate the different decibels between devices, we do not provide a specific solution.) 3.To avoid unnecessary loss, please SAVE your recording before exiting the sound meter app 4.If the recordings are not saved, you cannot replay the measurement.
