Three Acoustical Issues that Room Correction Can’t Correct




http://www.hifizine.com/2010/09/the-three-acoustical-issues-a-room-correction-product-can%E2%80%99t-actually-correct/

In a nutshell............

Issue number 1: place a subwoofer at the corners of the room.

To reduce the problem of speaker boundary interference
response(SBIR for short).

/I choose to have 1 subwoofer each in the front section of
the
room, 1 on the left corner and 1 more on the right corner.

/That's will be 2 subwoofers specifically used to for this
purpose
and not doing the main task of reproducing enough
bass contents
to add to the sound of the main speakers.
This helps explain 1 of
several reasons for the introduction
of additional subwoofers for
the sole purpose of reproducing
bass contents to emerge with
those of produce by the main
speakers, ie. integrate the bass
contents. A total of 7
subwoofers are in placed at the time of
writing.


Issue number 2: reduce/control of early sound reflections
from
the many surfaces of the room relative to those direct
sound
from the speakers.

/Work out a suitable combination of direct and reflected
sound
for that particular small room with acoustic treatments.
The level of reflections can only be controlled through
appropriate use of absorption or diffusion or by selecting
speakers.


/I choose the use of the ceiling treatments for a small room
and
at the 1st reflection point from the position of the speakers.
And
the choice of speakers happens to be very unorthodox.


Issue number 3: rt60 cannot apply in a small listening room.

The decay time of the room can only be brought to the level
needed for high quality sound reproduction through
appropriate
decorative choices, furnishings and the use of
acoustic
treatment..............

/A simple hand clap will tell! Reduce the long reverberation
time to bring up the sound quality, by reducing any overlapping
of sound to perceive much readily the time gaps between
individual sounds if any.

  4. The blog master has tolerate, so does the other writers and readers too........

    That blog master & writers are not knowledgeable enough and inexperienced.....it's still alright to voice what u think may be the case.

    Hinted that blog master & writers do not know how to listen and made a big mistake to feature some lo fi, brandless setups.........it's still alright u are entitled to your opinions and u are merely voicing your discontentment over the issue of not allowing lo fi setups a chance to be made known to the already very small population of audiophiles. That the writer(s) are just idiots to risk their reputations if there are any left at all!

    But the limit of tolerance may be reach with just having to read plain vulgarities directed at the good people here in this blog be it readers or writers. So much for the abuse of 'freedom of speech'!

  5. Hi Uncle Vic,

    Those/that knowledgeable and experienced "Anonymous" familiarly sounded like the legendary "knowledgeable" Hifi4sale forums MugenFoo and friends who have politely behaved in Hifi4sale forums lately after being condemned by their rudeness and arrogance. Sadly they haven't changed a bit in other blogs.

    Whether they are MugenFoo & friend or not, these Anonymous, to me, are the real coward, like rats, not brave enough to reveal their identities while claimimg how knowledgeable and superior to others.....What ! Knowledgeable Rats !!!......poor thing.

  6. Unker Vic,
    We've already track down this Anon's IP address and have located his whereabouts. It's only time before we search him up and give him a good fuck in the ass with a broom stick.

  7. Typical.

    A liar will never believe that there are honest men.

    A coward will always hit below the belt.

    And a man without a sex life will always taunt others about not having a sex life.

    This sad sod just don't want to feel lonely and that he is alone.

    Not everything is about sex. Get a life.

    You can call me Waiko.

  8. Room Acoustic treatment is a widely neglected aspect of this hobby.

  9. It's likely most audiophiles don't get the urge to do up the room acoustics. I said most, because I seldom see room acoustics being seriously considered, probably for reasons only or best known to themselves! I won't want to speculate here. The facts remained: I come across more listening rooms that are not done up, not even a wee bit than rooms that are done up to the brink!
