Melamine foam is a sponge made of melamine formaldehyde resin foamed through a fixation process. After compression at various pressures, actual density melamine foam will become melamine foam with various densities. The extensively used density of this type of foam is 8 and 12 density options.  The actual density of melamine foam is fixed at 8 densities, which is also the lowest density. The density will surge under high pressures of the compressor, but the weight remains unchanged, so this type of foam will have different kinds of densities. 8 density Sonex foam has an excellent benefit in the field of home decoration as acoustic material. Foam with 8 densities implies that in 1 cubic meter of space, the weight of the foam is 8 kilograms.  8 density foam composite can also be used for regular cleaning purposes along with being an acoustic material, like removing dirt, stains, and stubborn marks from surfaces like floors, walls and furniture.  This is the best foam pro...

Church acoustics reflect what a congregation believes are vital sounds. Church acoustics also unveil what church leaders think that people should hear. This is one reason Protestant Reformers changed their church buildings; they wanted to hear different sounds, such as a sermon. And these days, a church that uses a modern worship style will design a different space than a church that uses only acoustic equipments. Medieval church buildings Tall ceilings and stone walls create an echo space that is somewhat like being within the sound box of an instrument. The congregation can sink into an environmental cushion of sound, but they can’t hear crispy enunciated words or distinguish polyphonic musical lines.  Changing ideals in the protestant reformation Changing theological ideals changed the soundscape in Reformation era protestant churches. The congregation was meant to hear and realize the spoken words of the church leaders and the acoustics should work just like Municipal center a...

Over the years, I have got many calls from Gymnasium owners looking forward to enhance the sound in their spaces. Usually, gyms have many hard reflective surfaces and resulting lack of speech intelligibility. The first thought about sound control is generally acoustical wall panels, and these absorb sound but also water and hence, have one strike against them as people sweat in gyms and this creates much humidity, which demands for gymnasium acoustics . Initially, it appears counter intuitive not to treat the wall first. Well, isn’t the sound bouncing off the walls and across the room? True, but the typical gyms might have an echo time between three to seven seconds. While a reverberation is a discrete reflection, echo is a series on indistinguishable, non-directional reflections, and to prevent that in the gym you should look for gym soundproofing options.     The next stage is to control side-to side reflections by adding wall panels where a direct reflection creates a...
