What term deals with exactness of a measurement

Use precision in a sentence. Cutting construction paper hearts with precision using scissors. An example of precision used as an adjective is the term "precision tool" which means a device used to make concise measurements. The number of digits used to express the fractional part of a number. The more digits, the more precision. See single precision and double precision. See also accuracy. Sentences Sentence examples.

Future is about apps and not about the sound apps.!! Thanks for your article, I found it very educational and useful. Thanks again for your information. English translation: The ubiquity of smartphones and the availability of sound measurement applications may also present new opportunities for scientists and occupational hearing researchers. Excellent sound applications work on smartphones.

Science never ceases to amaze. Great article. Greetings and congratulations. I am an ear specialist.


I believe that everyone should download a sound meter on their smart phone, and urge others to do the same. This would help to avoid the hearing loss patients I see daily. Can you help?

I need a sound meter app for my web site and I am trying to find one that is available. The use of smart phones is ever expanding. I am a civil engineering student and have recently begun to find ways to use our phones to improve our ability to not only increase safety, but also efficiency. This research has encouraged me to review more apps, and see how to program new ones that meet my specific needs.

Thanks for sharing such great information with us. It is really a good research. Keep posting such more post.. It is nice information and thanks for sharing with us.

I like your post and it was good research about smartphones. Thanks for sharing amazing information. This page is a valuable resource! It also evaluated the accuracy of sound level measurement apps. Similar results were noted for one of the apps that was measured in the CDC study; however, some of the apps did not record results as accurately in our study as they did in CDC study.

Thanks for sharing this article. I appreciate you finding great sound apps of Smartphone. We chose 95 dB as the upper limit for our study because of our interest in typical occupational exposures. We are currently exploring the accuracy of apps with external mics, we have used them with acoustic calibrators generating dB at Hz and dB at Hz and the main apps from our previous study all performed well were able to measure those levels without any issues. I have read so many articles but I would say this is the one of the best article in sound measurement apps.

Nice post keep sharing. I really appreciate your work.

And all that I want to say is Keep sharing such useful information for us. This is the best article on Sound measurement Apps that I ever read! Can you write a similar article on other type of smartphones apps? If done, it would be nice work because people like us are waiting for such articles from high authority sites like yours.

Anyway thanks a lot. As a person with hearing loss, I agree with Dr. Grossan that everyone should have a way to know when the noise level around them is dangerous. We live in a very noisy world. I think there are OSHA regulations for noise in the workplace, but it is a shame that individuals have to have personal DB meters to know if the noise level around them is safe. Smoking has been banned in most public places because second hand smoke is dangerous.

Why do we allow noise levels in restaurants , bars, theaters, airplanes, and other public places that can damage hearing? Turn down the volume or give me my money back. Your posts is really helpful for me.


Thanks for your wonderful post. I am very happy to read your post. It is really very helpful for us and I have gathered some important information from this blog. Thank you very much for sharing this useful information. I was doing a project and for that I was looking for related information. Some of the points are very useful. Do share some more material if you have.

Loving the android platform over ios. Noise research needs more research to perfect sound applications. As a safety manager on a military installation, I appreciate these types of studies. I have used sound measurement iOS apps but never really had too much faith in their accuracy over our professional noise metering equipment.

I tend to use them just to get a preliminary reading if I think there is a problem. I also own a site where I have conducted reviews of some of these apps and the information here would be a great addition to what I have previously encountered. We use a kiosk that has a hearing test app on it.

We use it on a Microsoft RT tablet. It works really well. I hope that sound measurements continue to improve as well to help workers understand the noise around them. Thanks so very much for taking your time to create this very useful and informative site.

I have learned a lot from your site. I am very interested in how these apps perform in real-world environments compared to calibrated sound level meters. Is there a place where we can see what apps you have compared and their accuracy? Most of the apps I believe have the possibility to adjust the gain in order to be exactly calibrated at a specific frequency.

Typically 94dB at Hz. But in the posting here I can not see if this is done before the tests. Also it is often a problem at low levels that electric noise in smartphone apps using the built in microphones is around dB A. If you do not know the actual low limit at relevant frequncies then bevare.
