Mass loaded vinyl mat4/20/2023 ![]() ![]() Damping may cause wall Fr to fall into the woofer’s pass band and increase “box talk”. Box wall Fr and Q loss number lower than a well braced cabinet. Simplified design and construction, with increased net box volume vs. Resistance of wall panel is increased, lowering its Q and dissipating vibration through heat.Ģ. Fr of box vibration may not be raised above the crossover and the higher Q of the fr may produce more noticeable “box talk”.ġ. ![]() Added mass of bracing may largely offset the reduction in cabinet vibration, especially in a large cabinet.Ģ. Fr of box walls raised above the crossover of the driver occupying the box.ġ. Reduces cabinet wall vibration, lessening the through transmission of LF sound.Ģ. Without modeling software or a bit of trial and error, it’s all guesswork.ġ. In a large one, bracing may increase the Q and raise the fr of the cabinet walls right into the midbass range where it is most audible. Is the Mass Loaded Vinyl just an expensive way of saying rubber I wonder if there is any difference in gas flow resitivity specs I found a 100 rubber matt. Bracing on the other hand takes up as much or more internal volume in a small box. There simply isn't enough leakage from the tracking rooms at full roar to impact a mixing or tracking choice.A vinyl tile is almost viscous (bend one and see) and resistive to vibration. I've worked in a badass studio built on a single slab without floated floors. The latter can vastly increase complications and will not necessarily benefit the former. When it comes to studio building in the 21st century I'd lean more towards favorable acoustics over absolute isolation. I did 1/2 inch on top of 5/8 inch in my place. I don't know how MLV would function as underlayment but I don't believe it's intended to be used as such and could translate structure born sound through the floor in some cases.Īlso, maybe the science has changed on this but I seem to remember blending drywall thicknesses reduced structural resonance. If you did the same with floor underlayment it would not do much at all. If you put MLV on two sides of a single door with a good seal it would greatly reduce the sound that can pass through that door. MLV is reducing energy transmission by using a flexible mass to dampen energy conducted through a structure. The underlayment is reducing sound transmission via compression as a means of absorbing energy. ![]() Those two products do different jobs and the ratings aren't necessarily relevant to each other. Soundproof it from what? What are you trying to isolate? Sound getting in or sound getting out? I want to soundproof my floor and ceiling gap. TLDR: Floor underlayment has a higher STC level then mass loaded vinyl, but this seems wrong? I am confused and looking for anyone to expand upon this for me. Has anyone every used floor underlayment in place of mass loaded vinyl or know if the floor underlayment is more effective for deadening sound? So is floor underlayment a more effective sound deadener overall, This seems off to me. Mass loaded vinyl certainly has good characteristics, but floor underlayment apparently has a higher STC rating. I was looking at options for insulating and sound deadening. I am also raising the floor and green glueing in order to soundproof. I am doing a decoupled wall method 2 layers of 5/8 with green glue on all walls and ceilings. Hi there, I am in the middle of the studio build, and I want to soundproof my floor and ceiling gap.
