— WHAT IS SOUND ABSORPTION? —

Reduce Echo, Improve Room Acoustics

Sound absorption materials convert incident acoustic energy into low-grade heat. They are distinct from soundproofing (which blocks transmission between rooms) and from diffusion (which scatters reflections). Absorption is measured by α per octave band, summarised by the NRC single number rating (ASTM C423), and classified A–E by the weighted αw (ISO 11654).

  • Reduces echo, reverberation, and flutter inside enclosed spaces.
  • Improves speech intelligibility (STI) and listening comfort.
  • Targets octave bands 125 Hz – 4 kHz; product choice tunes the spectrum.
  • Measured per ISO 354 (lab) and ISO 3382-2 (in real rooms).
ⓘ Sound absorption improves room acoustics, while soundproofing systems are required to reduce sound transmission between spaces. See soundproofing solutions →

How Absorption Works — Three Mechanisms

Different absorber types tackle different frequency ranges. Real-world treatments often combine all three to cover the audible spectrum.

MECHANISM 01 SOUND POROUS FIBERS HEAT

Porous Absorption

Sound waves enter open fibers or cells; air friction inside the pores converts kinetic energy to heat. Best for mid-to-high frequencies; thicker product extends to bass.

250 Hz – 4 kHz · Broadband
In our range: Fabric · PET · Foam · Wood Wool · Baffles · Clouds
MECHANISM 02 VIBRATE SPRING CAVITY (AIR) PANEL (MASS) MASS–SPRING SYSTEM

Membrane / Panel Absorbers

A solid panel vibrates over a cavity acting as a mass-spring system. Tuned to the cavity depth and panel mass; targets specific low-mid frequencies that porous absorbers miss.

63 Hz – 500 Hz · Tuned Low-Mid
In our range: Perforated Wood · Grooved Wood (with cavity)
MECHANISM 03 AIRMASS CAVITY SLOT RESONANCE

Helmholtz Resonators

Air mass in a neck/slot resonates with the cavity behind it, absorbing energy at a single resonant frequency. Used in slotted panels to remove problem-frequency room modes.

Tunable Narrow · 80 Hz – 400 Hz
In our range: Slotted Wood · Perforated Wood (slot-tuned)

How to Read Absorption Ratings (NRC)

NRC (Noise Reduction Coefficient) is a single-number rating from 0.00 to 1.00 averaging absorption (α) across the 250, 500, 1000, and 2000 Hz octave bands. A panel with NRC 0.90 absorbs about 90% of mid-frequency sound energy that strikes it. Use NRC to compare materials quickly; use per-band α for design-grade calculations.

MATERIAL (INDICATIVE) NRC RATING
Acoustic Baffle Fabric 0.95
Acoustic Fabric Panel 50 mm 0.90
Acoustic PET Panel 24 mm 0.85
Acoustic Foam Panel 50 mm 0.85
Acoustic Ceiling Tile 0.75
Wood Wool Panel 25 mm 0.70
Perforated Wood Panel + Backing 0.70
Slotted Wood Panel + Backing 0.65
Drywall (untreated reference) 0.05
ⓘ Values shown are indicative — actual acoustic performance depends on the selected system, thickness, mounting method, and tested assembly. Yamamah Smart provides product-specific NRC tables and submittals on request.

ISO 11654 Class A–E Rating

European acoustic engineers use the αw (weighted absorption coefficient) and Class A–E rating from ISO 11654. Class A is the highest absorption category — recommended for studios, theaters, and broadcast spaces.

— CHOOSING THE RIGHT MATERIAL —

How to Choose Your Absorption Material

Selection depends on surface (wall vs ceiling), aesthetic, acoustic target (NRC and frequency range), and project context.

For Walls

Fabric panels, PET panels, perforated/slotted/grooved wood. Choose by aesthetic and room privacy.

For Ceilings

Acoustic ceiling tiles, baffles, clouds, and rafts. Choose by ceiling type and visual exposure.

For Studios

Thicker 75/100 mm fabric panels, bass traps, and foam — controls flutter echo and low-mid frequencies.

For Offices & Meeting Rooms

Mid-thickness fabric or PET panels on walls, plus ceiling clouds or tiles to reach 25–35% coverage.

For Eco / Sustainable Projects

PET (100% recycled polyester), wood wool, and moss panels — natural and recycled materials with absorption performance.

For Premium / Architectural Look

Perforated, slotted, grooved, or slat wood panels — warm natural finish for executive and hospitality spaces.

— FREQUENTLY ASKED —

Sound Absorption Questions

Q01 What is NRC and what's a good value? +
NRC (Noise Reduction Coefficient) averages absorption across 250–2000 Hz on a 0.00–1.00 scale. NRC 0.70+ is considered effective for general room acoustic treatment; thick fabric panels and baffles can reach 0.90–0.95.
Q02 How much wall coverage do I need to fix office echo? +
Typical office and meeting rooms need roughly 25–35% of hard-surface area treated with absorption (walls + ceiling combined). Highly reverberant spaces or large open offices may need more. We recommend coverage based on RT60 measurement or room model.
Q03 What's the difference between fabric, PET, and foam panels? +
Fabric panels offer the widest design flexibility and highest absorption when manufactured at 50–100 mm thickness. PET panels are 100% recycled polyester — cleanable, eco-friendly, and ideal for schools and clinics. Foam panels are budget-friendly and popular for studios and small treatments, but are typically not used as decorative finishes in commercial interiors.
Q04 Are your absorption panels fire-rated? +
Fire-rated options are available across most of our absorption product families, subject to the selected material specification and approved certification documentation. Request the data sheet and fire-test certificate for the specific product version you intend to use.
Q05 Can you customize colors, patterns, and shapes? +
Yes. PET panels are available in 67 YAMSIS colors and 50+ patterns. Fabric panels can be wrapped in hundreds of fabric references. Custom CNC shapes, geometric layouts, and printed graphics are available on request.
Q06 What is the difference between α, NRC, and αw? +
α (alpha) is the absorption coefficient at one specific frequency or octave band — a number between 0 (fully reflective) and 1 (fully absorbent). NRC (Noise Reduction Coefficient, ASTM C423) is the arithmetic average of α at 250, 500, 1000, and 2000 Hz — a quick single-number rating. αw (weighted absorption coefficient, ISO 11654) is a more rigorous single-number rating fitted to a European reference curve, paired with shape indicators (L, M, H) when the spectrum is uneven. αw also produces the Class A–E rating used in European projects.
Q07 Which international standards do your absorption products meet? +
Our absorption products are tested and rated per the relevant international standards: ISO 354 for laboratory absorption measurement, ISO 11654 for αw and Class A–E rating, ASTM C423 for NRC, ASTM E1264 for ceiling tile classification, and ISO 3382-2 for in-room RT60 measurement. Product-specific test reports and submittals are available on request.
Q08 What is RT60 and what's the target for my room? +
RT60 is the time (in seconds) for sound to decay by 60 dB after the source stops — measured per ISO 3382. Typical targets: classrooms ≤ 0.6s (ANSI/ASA S12.60); open offices ≤ 0.6s; conference rooms ≤ 0.5s; recording studios 0.2–0.4s; restaurants 0.6–0.9s; concert halls 1.6–2.2s. We measure RT60 on-site before and after installation and tune coverage to your target.
