MAD acoustical connections mass air decouple A typical graph will reveal that mid level frequencies and high frequencies are contained inside of the high TL assembly. Low frequency (LF) is difficult to stop. You can contain LF up to a frequency level as defined by how much mass you have in the assemble as a starting place. Other factors come into the equation to better define the TL. The distance between one side of the wall, roof, floor, etc. and the other side is called the “air”. Also builders insulation is placed inside...

If the word isn’t soundproof, what is it

Click here: If the word isn't soundproof, what is it? Digging holes and installing metal rebar, rolling out thick plastic sheeting, controlling 5 foot tall wire mesh in the attempt to place the wire in the concrete form. Controlling cracks in the concrete is what the wire does so tie it up good. Think the roof is just a roof? As they say, think again. The roof is typically part of the building envelope that you are trying to gain control over. Every sound outdoors will come in through the roof and walls and windows and doors. (more…)

It's not the playing ability, the 10000 hours have been put in. You are a competent musician and sought out by friends and family for your playing and singing and as often, your song writing ability. The room, the room doesn't know how to give back the music that your hands develop on your musical instrument of choice. What do you...

Glass critical frequency

Different thicknesses of glass in recording studio’s are used in a mass/air/mass configuration but it is not because they may rattle at the same frequency. The thickness of the material, any material, will have a critical frequency. This is an acoustic hole that allows sound/vibration to pass thru as if no barrier existed.

Acoustic treatment solutions for a mixing room First you want to make certain that you have your listening position set up as an equilateral triangle to produce the best possible starting position. Your speakers/monitors should be placed at a starting position 38% from the front wall as a starting position. First, let me cover why […]

Four Aspects of Sound Isolation

Four Aspects of Sound Isolation When it comes to sound isolation for your recording studio environment, you only need to keep four things in mind. Mass: The first line of defense in soundproofing Decoupling: Break the connections that sound vibrations use to get from one side of a wall to the other. Distance: Gain better […]

Optimized Room Ratios

Room Ratios The vast majority of folks attempting to develop a well isolated acoustically correct room will stumble on a few phrases that often make the process of moving forward difficult. One of these phrases will be “room ratios”. Why even consider the dimensions of a room and how it relates to sound? Since it does […]

Sound transmission loss

Sound Transmission Loss of Masonry Walls “The most common alteration made to the walls in these tests is the addition of layers of finishing materials, most frequently gypsum wallboard (sheetrock). One might imagine that the addition of extra layers of material to a wall could only improve its performance; this is not necessarily true.” ir586 […]
