spl meter vs app

I once again find myself spending a lot of time both reading and posting comments. Great article and study. In my thesis you Will find the references. Gov dogs didn’t get to point or give a straight answer, how can an app be as accurate as a sound meter? Is it safe to assume that the accuracy would improve on later iPhones, such as the iPhone6? Any of these apps should be adequate to do the job (The apps pricing range from $0.99 for NoiSee to $19.99/$99.99 for SoundMeter). Thank You. Nevertheless there are a lots of other smartphones out there. Using a quick, visual check using a controlled noise source that stepped by +20dB, some even appeared to be using a simple linear average. 1.Why you don’t speak about the hudge variability that’s posible to see in the figure 2 ? Very interesting discussion. You will be subject to the destination website's privacy policy when you follow the link.

Retrieved June 23, 2013, from http://www.nielsen.com/us/en/newswire/2013/mobile-majority–u-s–smartphone-ownership-tops-60-.html. Dan. The results of our study showed that the SPLnFFT app from Fabien Lefebvre and SoundMeter app from Faber Acoustical had the best accuracy, followed by Noise Hunter and NoiSee. This follow-up study suggests that using external, calibrated, microphones greatly improves the overall accuracy and precision of smartphone sound measurements, and removes much of the variability and limitations associated with the built-in smartphone microphones. This may be a good time to reiterate what we noted in the blog and in our published paper: “References to products, services, or apps do not constitute an endorsement by NIOSH or the U.S. government.”. It has an potential for empowering employees and ohs professionals. Also wondering what they cost & if they plot results for comparison metering. Thanks for your interesting article. Thank you for your comment, Michael. This was not the case few years ago when we did our first study. Another recent test of an sound level meter app using a new iPad showed a discrepancy of up to 10dB between measurements. Smartphone developers now offer many sound measurement applications (apps) using the devices’ built-in microphone (or through an external microphone for more sophisticated applications). We selected and acquired a representative sample of the popular smartphones and tablets on the market as of June 2013. I’m familiar with your app, and it’s wonderful to see some Android developers such as yourself put greater efforts in including appropriate metrics and advanced features into their applications. Thanks!! All useful stuff. In July 2013 I have tested several free apps myself mainly to see how my app SafeNoise was doing compared to other free apps. 2010]. Are you contributing trustworthy data? Nice blog. drgrossan@yahoo.com. 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. Functional used smartphones based on the less favored platforms are cheap enough — often under $10 U.S. — to beg the question whether lemonade can be made from these lemons? Making phones more friendly to repurposing can promote a number of societal benefits. Cirrus carried out its own brief survey among its customers to see if they are using any sound level meter apps and had considered the issue of accuracy. SPL Meter from AudioControl The noise reverberated downward. I feel you would be doing people at hearing damage risk a great dis-service by supporting the use of phone apps. The measurements were conducted in a diffuse sound field at a reverberant noise chamber at the NIOSH acoustics testing laboratory. Please see the November 2016 and January 2017 updates above, they point to our study on the use of external, calibrated, microphones to achieve closer agreement with a sound level meter. This article Seems to be nice. J. Acoust. Thanks for the great post.Very informative in relation to the future of voice commands. The orientation or positioning of the device has been shown in previous studies to be a significant factor upon the frequency response of the measurements. We live in a very noisy world. I really like your thoughts about sound apps of Smartphone’s. I have been exposed to 4 jackhammers continuous for hours on end at my work inside a interior metal roofed building. I work in a night club doing as best as I can for My Family with what I have. Applied Acoustics, 139, 119-128. https://doi.org/10.1016/j.apacoust.2018.04.011. So, can convenience or cost efficiency ever override accuracy when it comes to noise measurements? I actually used one of these apps to help decide the purchase of my last car. It describes the use of range-finding instruments and also strategies for monitoring compliance and enforcement. . Another issue was the variety of audio tools, chips, and microphones used by the different manufacturers, it would be great to understand if Samsung for example uses the same audio architecture across all its devices? It is linked in the text above or you can find it at http://scitation.aip.org/content/asa/journal/jasa/135/4/10.1121/1.4865269. Hope you article gets noticed by the sound app developers.. An interesting study, thanks for posting. For example, I could not expand the images enough to read many of the app names so the additional information buried in responses that identified the four best performing apps was very useful. For app selection, please see our detailed response to comment 12 below. I will keep visiting this blog very often. Useful! This article was exceptional … very useful, Great information, this is information about smartphone sound is useful.. Given the gravitation of users toward these two winning O/Ss plus mobile phones being on short cycles of obsolescence and replacement, there are an awful lot of still-functioning devices that are roadkill on the way to landfills or incredibly unsustainable recycling in China. Science never ceases to amaze. Nice Information….Great research on sound apps of Smartphone.
