Have you used smartphone apps of any type for workplace safety? Let us know in the comments. The cost of the four apps (rounded up to the nearest dollar): The LCD is about 9. However, owing due to that implies that it can’t be moved around often and is optimal for use if it is kept in one place. Want to measure sound level Decibel meter app shows a decibel values measuring the environmental noise and displays measured dB values in various forms. Noise measurement devices can cost $80 and up. This is a decibel meter that takes immense pride in its aesthetical value. What are the benefits of having these apps on smartphones? It’s to make employees more aware of the noise in their workplace (or, for that matter, while using power tools at home or when attending a concert).Īnd then there’s cost. The agency plans on extending this study to examine the effect of external microphones on the overall accuracy of sound measurement apps. NIOSH says external microphones such as the MicW i436 omni-directional measurement microphone comply with the sound meter standard. Newer iPhones allow users to connect external microphones through the headset jack when using these apps. No Windows phone noise apps met NIOSH’s standards either. Bouncy Balls shows students the volume of the noise in your classroom by displaying a set of colorful bouncing balls. If you don't have an iPad, you can find the same basic features in the following browser-based tools. Decibel Pro App is supported on both iOS and Android, so you can download it from Apple. The app measures the volume of the noise in a room and displays a meter indicating whether or not the the room is too noisy. This decibel meter app is known as one of the best sound measuring apps available for different types of devices. Therefore, NIOSH could not recommend a particular app for the Android platform. To discover the best decibel meter app, read about some of the most popular up-to-date programs. Yep, that’s the catch: Because several manufacturers make Android phones, there was a wide variance among the same app measurements on difference devices. NIOSH says these four apps may be considered adequate for certain occupational noise assessments when used on iPhones. Out of these three, SoundMeter had the best results. OSHA requires noise measurement instruments to have an accuracy of +/- 2 decibels (dB).įor unweighted sound level measurements, NoiSee, SoundMeter and SPLnFFT had mean differences within the +/- 2dB of the reference measurement.įor A-weighted sound level measurements, Noise Hunter, NoiSee and SoundMeter had mean differences within +/- 2 dBA (A-weighted decibels) of the reference measurement. The tests also compared results for i-Phones and Android phones. The National Institute for Occupational Safety and Health (NIOSH) evaluated the apps at its acoustic testing lab. The answer is, “Yes,” but only four apps that were tested measure up. Can smartphone apps, costing anywhere from $1 to $20, provide accurate occupational noise measurements? A new study provides the answer.
