Great explanations. And so true that there is no such thing as "absolute" soundproofing. Like you said, it's usually only managing / mitigation of certain frequencies.
Yes. Noise transmission issues can be divided into two main frequency ranges. We have < 125 hz. and > 125 hz. Noise < 125 hz. requires much more mass, numerous layers and more space requirements. The density of each layer must be arranged in the proper order or sequence to deal with lower frequency pressure waves and their associated vibrational signatures. Noise above 125 hz. and its associated vibrational signatures requires less mass, less layers with smaller densities. One size does not fit all noise.
Thanks, Dennis. There's just so much misinformation out there, and you provide real info. I've actually built 'soundproof' rooms (SCIFs). Very expensive and these were just for the F and A of voice. No way will a 2 x 6 stud wall, with 2 layers of "green glue" even sufficiently stop voice transmission.
I'm trying to convert a outdoor garage to mix Drum and Bass. Are acoustic insulation and acoustic plaster boards a waste of money ? Great video by the way 👏
You will need to take noise numbers in the neighborhood. I can simulate the noise produced in your drum room. What I dont know is what is going on in the neighborhood. We have processes where you use your cell phone to take the noise numbers over a week so we can pressure map the noise for any time usage.
Moving my business into a new building, we are a live production company [sound, lights & video]. We have a rehearsal/pre-production room where artists come to rehearse prior to tours, etc. The new room will be 50' x 80' with 35' walls [to the existing ceiling as we need access to the steel for rigging] What would be the most cost effective way to build this room to minimize or reduce 40Hz-125Hz? Being commercial I may have to use metal framing in lieu of wood. This is not our primary revenue stream but a side hustle that supplements our equipment rentals...

30 years ago I was into high quality audio reinforcement, and I built an audio system in my car that reproduced a soundstage across the dash. If you closed your eyes you could hear locations of instruments and any movement across the stage as well as sense the acoustic size of wherever the music was recorded or however the producers and engineers designed it for the album. Part of that clarity and reproduction accuracy involved sound "proofing" but I always referred to it as sound deadening. I knew there was never any hope of driving around in a sound *_proof_* car so it never felt right to call it anything but sound deadening.
We see that the term sound deadening is used more on the absorption side of issues. A room is too dead usually implies the wrong rate and level of absorption and too much surface area coverage thus producing overabsorption. Sound damping is usually used for noise transmission issues. Neither one are accurate.
@@AcousticFields True. And in a moving vehicle it's an exercise in futility. However, I tested with an SPL meter and before I applied sound proofing the ambient noise level inside the car with the windows up on the highway was around 90 - 94 dB, and after it was down to about 87-89 dB. So it definitely helped with the "dynamic headroom" of the overall sound system. I guess damping is the more accurate term for soundproofing a car. It was mostly about adding mass to body panels by applying thick tar strips and panels and a dampening paint that was basically a thick rubberized material once it dried.
Might the use of manufactured T-Studs 2x6 or 2x8, etc add additional structural strength to walls when building as part of a plan to manage sound parameters in new construction?
What are the frequency and amplitude of your noise issues. Without noise numbers, you are guessing and guessing is a fool's game when it comes to noise.
@@AcousticFields Also the size of the maximum unanchored span effect this, also. A wall that is 40X40 feet will be harder to attenuate than a wall that is 4X4 inches.
What are the frequency and amplitude (strength) of your noise issues? Every noise issue requires a number or you are just guessing and with noise guessing wrong usually means treaing out what you built and starting over.
@@panca4238 All material and constructuction methodologies are based upon the frequency and amplitude of the noise you are dealing with. There is no good or bad. These are misleading terms.
Yes, but we don't work in airless chambers. It might be easier if we did but we have to stay focused on the energy conversion process that occurs when airborne energy strikes a wall and the science becomes vibrational acoustics.

Another half truth perpetuated by the industry to sell tactics that will not work because they can not work.

I've actually built 'soundproof' rooms (SCIFs). Very expensive and these were just for the F and A of voice. No way will a 2 x 6 stud wall, with 2 layers of "green glue" even sufficiently stop voice transmission.
Lower frequency noise transmission requires multiple layers with proper density of each layer.

Thank you!

Good video!
Have you heard anything about Sonopan? Seems to be the next thing in homes to absorb sounds.
What are the frequency and amplitude of your noise issues. You must match the barrier technology used to the noise.
Hello, how about tripple leafs constructions, is it bad? Always bad?
Thanks

@@AcousticFields traffic noise, i am not try to build it, just ask about tripple layer constructions, what your opinion about it.
Thanks

👌👍
Thank you for your continual support. We all appreciate it even though we do not say it enough.
A perfect vacuum is soundproof. However, the edges of the chamber in which vacuum is maintained can transmit sound.
Yes, but we don't work in airless chambers. It might be easier if we did but we have to stay focused on the energy conversion process that occurs when airborne energy strikes a wall and the science becomes vibrational acoustics.
