The Problem with Fibrous Acoustics

Non-Fibrous, Non-Degrading Acoustic Solutions

Conventional acoustic materials rely on porous fibres that absorb moisture, degrade over time, shed dust and lose acoustic performance — creating long-term problems in HVAC plants, DG rooms, infrastructure corridors and industrial environments.

Micro Acoustics solves this with micro-perforated panel systems engineered on Helmholtz resonance and transfer impedance principles.

  • Stable acoustic performance that does not fade with age
  • Hygienic, dust-free operation with no fibre shedding
  • Fire-safe & moisture-resistant all-metal construction
  • Long service life with negligible maintenance

Why Choose MPP

Built for Demanding Environments

Geometry-driven acoustics that outperform and outlast traditional fibrous and foam absorbers.

High, Tunable Absorption

Design NRC of 0.70–0.95 by tuning hole diameter, pitch and cavity depth — independently verified at NRC 0.90.

Fire-Safe & Non-Asbestos

All-metal, non-combustible construction with no flammable fibre load — ideal for plant and DG rooms.

Moisture & Mould Resistant

No water absorption and no organic fibre means no mould growth, even in humid HVAC and outdoor duty.

Hygienic & Washable

Smooth, dust-free surfaces can be wiped or washed clean — suited to healthcare, data and food-grade spaces.

Lightweight & Durable

Monolithic flat-plane panels are easy to handle and install, with prolonged performance and minimal upkeep.

Aluminium, SS & GI

Manufactured in 1 mm aluminium, 0.5 mm stainless steel and 0.5 mm galvanised iron to suit any environment.
