Before & After Acoustic Treatment 

Measured, Not Assumed

The following measurements were taken in the same room, same speaker position, and same measurement position, before and after applying proper acoustic treatment.


No electronic EQ or calibration was applied.
The difference you see is purely the effect of acoustic treatment.

Understanding the Measurement Shown (RT60 & Decay)

RT60 represents the time it takes for sound energy to decay by 60 dB inside a room.
In home cinema and critical listening spaces:

  • Too long decay → muddy sound, poor dialogue clarity

  • Too short decay → dry, lifeless sound

  • Uneven decay across frequencies → tonal imbalance and listening fatigue

A well-treated room shows controlled and consistent decay across frequencies.


BEFORE Acoustic Treatment

(Untreated / Poorly Controlled Room)



What the Measurement Shows

  • RT60 ≈ 0.64 seconds

  • Excessively long decay, especially in low and mid frequencies

  • Energy persists for a long time after the sound stops

  • Uneven decay behaviour across the spectrum

What This Means Audibly

  • Bass sounds slow, boomy, and overlapping

  • Dialogue lacks clarity

  • Sound feels loud but not controlled

  • Effects and music smear together

  • Listening fatigue over longer sessions

In this condition, even the best speakers cannot perform correctly, because the room dominates the sound.


AFTER Acoustic Treatment

(Properly Designed & Treated Room)



What the Measurement Shows

  • RT60 reduced to ≈ 0.30 seconds

  • Faster and more uniform decay across frequencies

  • Excess energy is absorbed and controlled

  • Clean, predictable acoustic behaviour

What This Means Audibly

  • Bass becomes tight and articulate

  • Dialogue is clearer and easier to understand

  • Sound stops when it should stop

  • Better separation between effects, music, and vocals

  • Comfortable listening even at higher volumes

This is the foundation required for reference-level sound reproduction.


The Real Takeaway

Acoustic treatment alone achieved:

  • ~50% reduction in decay time

  • Massive improvement in clarity and control

  • A room that now supports high-performance audio

No DSP, no EQ, no calibration can replace this step.


Why Acoustic Treatment Comes First

Acoustic treatment:

  • Controls reflections

  • Reduces resonances

  • Manages decay time

  • Makes the room predictable

Only after this stage does any electronic processing make sense.


Final Words

These measurements clearly demonstrate that:

Great sound does not start with equipment — it starts with the room.

At Great Sound Acoustics, our focus is on measurable acoustic performance, not assumptions or cosmetic solutions.

When Design Looks Perfect but Sound Fails

Many home theaters look stunning.
But when you actually sit and watch a movie — especially during action scenes — the experience can become fatiguing, irritating, even headache-inducing.

The reason?
Sound that is  acoustically uncontrolled.

Audio preference varies from person to person, and most homeowners are experiencing a dedicated cinema for the first time. They may not be able to judge whether the sound is truly accurate — even when it’s described as “the best audio in the world.”

But measurements don’t have opinions.
They don’t exaggerate.
And they don’t lie.

In one of our recently completed projects, we measured the RT60 response across the entire frequency spectrum — not just a single band.
The result?
Every band was within the recommended limits.

RT60 of Home Theater

This level of consistency doesn’t happen by chance.
It is the outcome of:
• Acoustic expertise
• Thoughtful design
• Precise execution
• Deep involvement at every stage

This is how exceptional results are achieved — even with ordinary equipment.

Because in cinema design, knowledge matters more than brands.

Why Sound Absorption Required in Home Theater

Sound absorption is first step to improve sound, but Thickness matters. Any room will have problem below 1000 Hz and not in the high frequency. 1 inch panel absorption will starts from 1000 hz and above and 2" panel starts absorption from 500hz and above. We recommend minimum 3" panels for board band absorption which will start absorption from 250Hz and above. We have Curve 75 which is 75mm thickness and the size is 2 by 2 ft. Its Velvet Coated Unique Foam and the size, color, design can be customized as per your choice. It can be placed in front wall to absorb the reflection coming from the rear wall, In rear wall, you can place in center to absorb the center channel and of course in celling between front row and the screen. Always make sure you place the curve 75 above 2f from the floor and you should cover up to ear height.  if your RT60 is high than you can place more panels in front wall to control RT60. Dont get confused by NRC values, NRC will vary depending on Frequency. For 1" panel, the NRC at 1000HZ could be .95 or 0.99 but for 500Hz it may be for .3 or .4 and 250Hz it could be 0. So please take a note while designing your hifi systems.
