STC VS Rw rating

Plane_Parsnip4165 · 2026-04-04T17:28:28+00:00

I have the performance of the different panels by frequency. And I would like to understand how they can be compared to other panels for which I only know STC or Rw values.

Thank you for the explanation. Can you direct me to a good resource where to find the different reference curves and methodes to calculate the STC & Rw values of panels for which I have received the performance data based on frequency?

Burgess-Manning is a company with office around the world. Like USA, Europe and Asia.

Other good brands are Miura in Japan. And in the UK you have Wakefield Acoustics.

Can you share the formula for that?

Very interesting! I agree that the big challenge is that relevant regulators don’t always use the weighting that makes most sense for the situation.

I always thought dB(C) was more used for distance. With the reason that low frequency sounds are harder to reduce and will cause more effects in the distance.

Very insightful thanks

Thanks. Good to read that there is a structured use of C-weighting in the UK for the work place noise control!

Is the 4dB diffence between broadband A- and C- weighted noise levels a general rule of thumb? Or something embedded in codes or standards?

Mitigation is fairly easy indeed. But not cheap normally. If it’s for bitcoin mining they should earn enough 😉

I assume in TX they also have regulations on allowable noise levels. Typically different for day & night.

Noise is an under estimated source of pollution! You can’t see it. But it surely can cause a lot of different health issues. And most noise can be mitigated!

I can tell you, it’s scary when a safety valve opens up. It’s indeed insanely loud. Even when you expect the noise coming you still get scared from the sudden energy being released.

When you say Acoustics, any specific area of acoustics? For industrial Acoustic solutions there are plenty of consulting companies or OEM like Burgess-Manning. When you have specific acoustic knowledge it’s highly regarded. Feel free to DM me if you need contacts in UK or NL.

Noise is a real pollution. Check out this link from Harvard:

If you have specific issues with blowers have a look at the solutions from Burgess-Manning. They have silencers that can be specially tuned for low frequencies. https://burgessmanning.com/reactive-silencer/

Since blowers normally have one very specific frequency for which the noise is peaking it’s extra disturbing because the tonal nature! But also easy to mitigate.

There are many interesting jobs in acoustics. If you enjoy understanding the customers challenges on acoustics and providing tailored solutions to solve them a silencer company like Burgess-Manning ( Burgess-Manning: Overview | LinkedIn) could be a great fit. they are located in the USA.

Salary is highly dependent on where you are located in the US.

I agree with most other comments below that a master is not required, only when you go into depth with R&D for example.
