Your Acoustics Checklist

April 25 2019

It is imperative that you plan ahead and clearly scope out your requirements in view of making the right product system specifications at the conceptual stage of your project.
Retrofitting acoustic panel systems following completion can be expensive, time-consuming, can interfere with schedules and often has a ‘Band-Aid’ look about it. Hence the need to clearly delineate and analyse potential issues beforehand in view of intelligently addressing them at the most appropriate time.

PLAN AHEAD

What you need to know:

  • Room dimensions
  • Ceiling height
  • Type of lighting
  • Ventilation/Ductwork
  • Fire rating requirements
  • Environmental accreditations required
  • Potential issues
  • New Build or Retrofit?
  • Current sound treatments

DIAGNOSIS

What are your main sound issues?

Part One:

  • Echo
  • Excessive Noise
  • Reverberation
  • Sound Quality
  • Speech Intelligibility
  • Hearing Protection

If any of these are critical issues, you will need SOUND APSORPTION products.

What are your main sound issues?

Part Two:

  • Sound Transfer
  • Low Frequencies
  • Impact Noise
  • Vibration Noise

If any of these are critical issues, you will need SOUND ISOLATION products.

ABSORPTION TREATMENT

It is vital that the correct level of absorption is ascertained.

  • Light Absorption
    Approximately 5% – 25% coverage is required. Typical applications include
    recording studios, interview rooms, conference rooms, offices, etc.
  • Moderate Absorption
    Typically 25% – 50% coverage is required. Suits theatres, open plan offices, etc.

Heavy Absorption

505 – ϭϬϬ% Đoǀerage. This is for ͚heaǀy duty͛ appliĐatioŶs suĐh as ŵusiĐ rooŵs,
vocal booths, recording isolation booths, and other areas that require almost total
absorption.
Absorption materials should be installed so that they are exposed to the
source of the noise problem for it to work most effectively. In most applications,
they work best if they are positioned evenly around the space you are treating.

ISOLATION TREATMENT

Some recommendations for sound isolation include:

  • Look for areas where sounds may be escaping through. Doors, windows, ductwork,
    vents are the common culprits.
  • Employing thicker, less compressed materials to reduce impact and/or vibrational
    noise.
  • Thinner, denser materials work best for sound isolation.
  • ‘Seal’ the room. Make every effort to cover every surface with an appropriate sound isolation material to prevent sound escaping or entering.

Sound isolation materials need to be installed between wall layers.

For new buildings, isolation materials can be attached directly to wall studs or floor joists.
For retrofit applications, isolation materials may be added to existing walls followed by
additional layers of plasterboard over it the more mass, the better the outcome!
