Acoustics

Wave is the Australian distributor of PhoneStar — a German-engineered soundproofing board used in floors, walls and ceilings to cut both impact and airborne noise.

PhoneStar by Wave

A heavy, honest board that quiets the rooms it's built into.

PhoneStar is a dense acoustic panel made from corrugated cardboard cells filled with kiln-dried quartz sand. The mass does the work — converting sound energy into heat as it passes through the board.

It's been used across Europe for over twenty years in residential construction, multi-storey apartments and high-end media rooms. Wave brings it to Australia through a national network of acoustic and flooring retail partners.

Made in Germany · From recycled cardboard and quartz sand.

How it works

Mass, not foam.

Most acoustic products rely on soft foam to absorb sound. PhoneStar takes the opposite approach — a heavy, dense board that physically blocks sound from transmitting through the structure.

  • 01 — Cellular structure

    Two outer layers of dense, recycled corrugated cardboard form a rigid, honeycomb-style cell matrix that holds everything together.

  • 02 — Kiln-dried quartz sand

    Each cell is filled with kiln-dried quartz sand. The sand adds mass (~17 kg/m²) and absorbs vibration as sound moves through the panel.

  • 03 — Energy converted to heat

    The combination of mass and damping converts airborne and impact sound energy into tiny amounts of heat — instead of letting it pass through to the next room.

A 15mm board that performs like 90mm of conventional build-up.

PhoneStar achieves significant Rw improvements in just 15mm of build height — critical when retrofitting existing floors and ceilings where you can't lose room height.

Tongue and groove edges interlock without fasteners, and the board cuts cleanly with a standard handsaw or jigsaw — no specialist tools, no dust extraction rigs.

Use cases

Where PhoneStar goes in.

PhoneStar installs into floors, walls and ceilings — in new builds, renovations and retrofits. A short list of the projects we see it specified into most often.

  • Apartments & townhouses

    Impact noise between floors is the most common complaint in multi-storey living. PhoneStar laid under timber or tile reduces footfall and dropped-object noise to the unit below.

  • Home theatres & media rooms

    Used in walls and ceilings to contain low-frequency content from subs and surrounds, keeping movie-night out of the kids' bedrooms upstairs.

  • Recording & podcast studios

    Combined with absorption inside the room, PhoneStar provides the structural isolation a studio needs — stopping street noise getting in and tracking getting out.

  • Home offices & study nooks

    Walls between an office and a shared living space, or between two work-from-home rooms, get a noticeable lift in privacy with a single layer of PhoneStar.

  • Hotels & short-stay

    Specified into wall and floor systems to hit Rw targets in hospitality fit-outs where guest experience is non-negotiable.

  • Renovations & retrofits

    Thin enough (15mm) to add to an existing floor without losing meaningful head height — ideal for character-home and warehouse-conversion projects.
