Which of the following is an example for bad reflector of sound?

Which of the following is an example for bad reflector of sound?

Bad reflectors of sound – Thick curtains, thick carpets.

Is asbestos a good reflector of sound?

Asbestos insulations are very diversified. Asbestos applied in this manner provides for thermal insulation, fire protection, sound insulation, resistance to corrosion when metal surfaces are covered, and elimination of wall “sweating.” For sound insulation and acoustical purposes, fiber up to 1 /2 in.

What wood absorbs sound the best?

Generally, wood is good at sound absorption because it’s porous, with plenty of air spaces to trap sound….The most soundproof wood types are:

• Cork.
• Acoustic plywood.
• Medium Density Fiberboard (MDF)
• Oriented Strand Board (OSB)

Does solid wood absorb sound?

Sound Absorption Wood isn’t a dense enough material to absorb much sound as is. However, wood with holes, grooves or slots cut into it becomes a perforated resonator that does reduce sound. Enhancing the porous nature of wood improves its sound absorption ability.

Is cement board good for soundproofing?

Cement board is also very dense which makes it an excellent insulator against airborne or impact noises. Since cement board is heavier than gypsum, it is harder for sound to move through it. It helps to make cement board more soundproof.

Does Styrofoam absorb vibration?

Polystyrene foams such as Styrofoam can help muffle and reduce the presence of any noises from outside the immediate room or environment. Sounds are simply vibrations, and polystyrene absorbs these vibrations, or sound waves.

Does Styrofoam stop vibration?

thick, can substantially reduce structure-borne vibrations before they produce annoying sound or destructive resonance. It also reduces vibration. Vibration dampers and sound-absorbing foam should be selected so they both absorb in the same low-frequency range produced by the machinery.

Is foam good for vibration?

Capable of attenuating vibration on any level, ethereal studio sound to high-impact industrial shock, foam dampens energy transmissions through physical mediums.
