Loudness meter?

The article suggests that human-perceived loudness is better measured by a loudness meter, but the entry for that item refers to measuring the loudness of a broadcast program, not an acoustic environment. Is there a standard for an acoustic loudness meter, and do they exist? — Preceding unsigned comment added by 78.133.236.129 (talk) 10:41, 11 May 2015 (UTC)

I was wondering about that. There is a standard for an acoustic loudness meter (ISO 532 series covering the Zwicker and Moore-Glasberg loudness metrics) but they are not common hand-held devices. The unit of loudness (long before ITU defined LU) is the sone, or its logarithmic counterpart phon. Normally acoustic loudness measurements are made by applying analysis software to a calibrated pressure recording -- only recently has it been practical to make a portable realtime acoustic loudness meter as the processing required for reasonable accuracy is quite involved.

cost of meters

im glad to see a mention of cost to give readers an idea of they could expect to pay for an accurate meter in noise pollution cases :

"Inexpensive sound level meters (under $200)"

i'd like to see more costs given for various types of meters. . 98.110.40.14 (talk) 16:20, 26 June 2016 (UTC)

Handheld vs Others

On the basis that sound level meters are commonly also NOT handheld would it be more accurate to define sound level meters as traditionally handheld? For example, BKSV have since the 1980s deployed many units around airports that are anything but handheld and other manufacturers also produce units that are distinctly intended for permanent or semi-permanent deployment.

I would say that these permanent or semi-permanent units are perhaps more aptly described as measurement "stations" as they are much more than the sound level meter components alone and that the concept of "sound level meter" is still commonly associated with a handheld device. "Traditionally" could be a more fitting word, but this may dissolve into a pedantic discussion. :)

Why nominated for deletion?

I'm a newby to Wicki editing. What does it mean that the discussion on the potential deletion of the page "sound level meter" had been re-directed? Where? This seems like a valuable page to me. I can't find any other page describing these devices. I logged on in order to suggest an edit: In the following sentence, "10 times" should be replaced by "20 times": Formally, LAT is 10 times the base 10 logarithm of the ratio of a root-mean-square A-weighted sound pressure during a stated time interval to the reference sound pressure — Preceding unsigned comment added by Ad000000 (talk • contribs) 21:14, 10 January 2019 (UTC)
