Acoustic panels are sound absorbing wall and ceiling boards made from glass wool, PET fibre, wood fibre, or perforated wood and metal cores that reduce echo, reverberation, and background noise inside a room. Packsound manufactures acoustic wall panels, acoustic ceiling panels, perforated acoustic panels, and PET acoustic panels with NRC ratings from 0.70 to 0.95, engineered for offices, studios, auditoriums, hospitals, and homes across India. If you need a fast answer: acoustic panels improve how a room sounds, they do not stop sound from entering or leaving that room. For that, you need soundproof acoustic panels or mass loaded construction, which Packsound also designs on a project basis.
What Are Acoustic Panels?
Acoustic panels are engineered boards fixed to walls or ceilings that absorb sound energy instead of reflecting it back into a room. When sound waves strike a porous or perforated surface, friction inside the material converts sound energy into a trace amount of heat, which lowers reverberation time and reduces perceived noise. This is the same absorption principle used in recording studios, cinemas, and concert halls, scaled down for offices, classrooms, and homes.
Acoustic Panels vs Soundproof Acoustic Panels: What's the Real Difference?
Acoustic panels treat sound quality inside a room. Soundproof acoustic panels, along with mass loaded barriers and sealed partitions, stop sound from crossing between rooms. Most professional projects need both, specified separately, because absorption and blocking are two different physics problems and no single thin panel solves both at once.
Types of Acoustic Sound Panels Packsound Manufactures
Perforated Acoustic Panels
Perforated acoustic panels use a wood, MDF, or metal face with a pattern of drilled holes over an absorbent backing. The perforation ratio (usually 10 to 23 percent open area) determines how much mid and high frequency sound the panel absorbs, while the backing material handles the rest. These are the most requested acoustic wall panels for corporate interiors because they combine visible wood grain with real acoustic performance.
PET Acoustic Panels
PET acoustic panels are made from recycled polyester fibre, compressed and thermoformed into rigid or semi rigid boards. They carry no glass fibre, are formaldehyde free, and suit schools, healthcare interiors, and eco certified green buildings such as LEED and IGBC rated projects. PET acoustic panels perform best above 500Hz and are frequently paired with a thicker bass trap in rooms with low frequency issues.
Acoustic Ceiling Panels and Ceiling Mounted Acoustic Panels
Acoustic ceiling panels, including baffles, clouds, and perforated tiles, are ceiling mounted acoustic panels suspended or grid mounted above the occupied space. In open plan offices and auditoriums, ceiling coverage frequently reduces reverberation faster than wall panels alone, since sound striking a hard ceiling reflects directly down onto occupants.

| Myth | Reality |
|---|---|
| Acoustic panels fully soundproof a room | They absorb internal echo, they do not block external noise |
| More panels always means better acoustics | Over-treatment kills natural sound, target RT60 matters |
| Foam egg-crate panels work as well as engineered panels | Foam targets only high frequencies, ignores bass and mid-range |
| Acoustic panels must look industrial or ugly | Premium wooden and fabric panels enhance interior design aesthetics |
| Any panel works for any frequency | Bass below 250Hz needs thick (75–100mm) or corner-mounted treatment |
| Acoustic panels are a luxury for studios only | Offices, schools, and hospitals benefit equally and often more |
| DIY installation gives same results as professional design | Placement, coverage area, and room geometry determine outcome quality |
Frequently Asked Questions
Do acoustic panels actually work for reducing noise in a room?
Yes, acoustic panels reduce internal echo and reverberation, not external noise transmission.
What is the difference between acoustic panels and soundproofing panels?
Acoustic panels absorb internal reflections; soundproofing panels block sound between rooms.
How many acoustic panels do I need for a 12x12 room?
Typically 25-35% wall coverage, around 8-12 panels of 2×4 feet size minimum.
Can I install acoustic panels on the ceiling instead of walls?
Yes, ceiling placement is often more effective for open-plan offices than wall-only treatment.
Are wooden acoustic panels better than foam panels for offices?
Wooden panels offer better broadband performance, durability, and aesthetics than foam.
What NRC rating should I look for when buying acoustic panels?
For offices and studios, choose panels with NRC 0.80 or above for meaningful results.
Do acoustic panels help with bass and low-frequency sound problems?
Only thick panels (75-100mm) mounted with an air gap effectively treat low frequencies.
Can acoustic wall panels be used outdoors or in humid environments?
Only panels with moisture-resistant substrates (HDHMR, metal) are suitable for humid areas.
How much do acoustic panels cost per square foot in India?
Professionally engineered panels range from Rs 90 to Rs 600 per square foot depending on type.
Is it worth hiring a professional for acoustic panel installation vs. DIY?
Professional acoustic design ensures correct coverage, placement, and measurable RT60 outcomes.
