Acoustic

The importance of acoustic is not less than hifi in hometheater , but unfortunately it is

Considered rarely and most of the reviewers want most sound and picture in a hometheater system.

One of the points which should be considered is the efficiency Rate of voice in a hifi system or in a hometheater which has straight relation to the acoustical condition of the place.

If your hometheater system sets in the non acoustic room, the efficiency of the DSP power and its effect on audience will decline extremely.

Accurate using of rockwool on the floor and roof will increase the resolution of sound channels extremely and it causes to feel a sound effect when it is starting until fading.

Set the diffuser on the back of main speakers left and right walls and back of the hall has an effective help to control the sounds in hall.

In the flats or small house isolating the roof and floor is pretty hard so we could use diffuser pieces which are ready for use, if they set correctly, you have well result too.

I should say that correct place of diffuser depends on the room dimension ,kind of speakers, distance between walls, you should not buy some diffuser and set the on those places then expect well result because this work needs lots experiences to find the best place on any walls.

Similarly that lack of suitable diffuser in the hall has negative effect on the sounds, bad using of diffuser or consumedly has worse effect than its lack.

If in the isolated room is used lots diffuser and in appropriate places system efficiency decline specially it has negative on of sound power.

Created sound from a sound source because of clashing to the walls roof floor and furniture reflexes then is heard, it is because of this when we speak in an empty room our voice has lots reflexion, but when furniture add this reflexion  decreases dramatically.

Created sound from a hifi system or a hometheater is heard because of spreading from mentioned sources.

Measuring of loyalty of a sound to its source has straight relation to acoustical condition and place of spreading.

In hometheaters if sound has lots reflexion sound effects will be twisted and audience can not feel well resolution and perfect moving of the sound effect from the start point until fading, it will cause we think our amplifier or the system has a weak DSP power.

If a room covers with lots diffuser spread sound from speakers will be absorbed lots and we have not accurate reflexion and the result is less sound power, the sound effect cut during moving between tow channels .

A room which has a controlled reflexions increases the sound system power dramatically, so we have sweet and neutrality sound in music and more dynamical 

Effect with high vibrancy in movie

good luck
