You can enable or disable noise levels data exporting to Health app in dB Meter Pro app settings. Integrated Fully Functional Spectrum Analyzer.Allows you to save, export and play back recorded measurements.Export measurements in CSV or Audio format.Save measurements with custom names and rename existing measurements.Saves location data for each measurement.Enables you to overlay the ambient noise level onto photos and videos and to export the results.In the event your daily permissible dose of noise is exceeded, use Noise-absorbing headsets or Earplugs. Noise dosimeter will help you understand how noisy it is at home and at your workplace.Export measured noise levels and audiogram directly to Health app. "The best way to meter sound levels" - AppAdvice (Please note that dB Meter Pro app is not a replacement for professional devices and should be used for personal purposes only.) dB Meter couples utility with stylish design and a polished user experience: a powerful tool in a sleek package, and at a tiny fraction of the cost of professional sound level meters. With dB Meter, you can measure ambient noise levels, save your measurements and their locations, and share your measurements with others. Sound level meters are useful for anyone who wants to avoid exposing their ears to harmful noise levels, but who wants to spend hundreds of dollars on one?ĭB Meter is free app which provides professional-quality measurement results, calibrated using an actual Nor140 high-precision decibel meter. The world is a noisy place: cars, power tools, crowds, machinery, and other common sources produce amounts of noise that can, with continued exposure, lead to permanent hearing loss. This scale is used particularly in applications where sound travels in water.DB Meter is full of features sound level meter with exclusive accuracy of measurements plus Hearing test, Noise dosimeter, Spectrum Analyzer with RTA, FFT & Spectrogram.ĭecibel Meter Pro is full of features sound level meter with exclusive accuracy of measurements and integrated Spectrum Analyzer. It should be noted at this point that there is another decibel scale in use, called the sound pressure level, based on the ratio of the pressure amplitude to a reference pressure. For example, a 56.0 dB sound is twice as intense as a 53.0 dB sound, a 97.0 dB sound is half as intense as a 100 dB sound, and so on. In equation form, intensity I is I=\frac\\ is given (and not the actual intensities), this result is true for any intensities that differ by a factor of two. Power is the rate at which energy is transferred by the wave. Intensity is defined to be the power per unit area carried by a wave. The relevant physical quantity is sound intensity, a concept that is valid for all sounds whether or not they are in the audible range. High noise exposure is hazardous to hearing, and it is common for musicians to have hearing losses that are sufficiently severe that they interfere with the musicians’ abilities to perform. In cartoons depicting a screaming person (or an animal making a loud noise), the cartoonist often shows an open mouth with a vibrating uvula, the hanging tissue at the back of the mouth, to suggest a loud sound coming from the throat Figure 2. We are all very familiar with the loudness of sounds and aware that they are related to how energetically the source is vibrating. But when a passing motorist has his stereo turned up, you cannot even hear what the person next to you in your car is saying. After settling into bed, you may hear your blood pulsing through your ears. In a quiet forest, you can sometimes hear a single leaf fall to the ground. Noise on crowded roadways like this one in Delhi makes it hard to hear others unless they shout.
