Quick answer: To fix bad acoustics, first name the problem: echo (sound lingers), boom (bass builds up), harshness (bright, ringing sound) or noise coming in from outside. Echo and harshness are fixed with acoustic panels near people, on facing walls and the ceiling. Boom needs bass traps (thick corner panels that soak up deep, boomy sound) in corners. Outside noise needs soundproofing such as seals and heavier doors.

Key takeaways

  • Diagnose first: echo, boom, harshness or outside noise.
  • Panels fix echo and harshness; bass traps fix boom.
  • Outside noise is a soundproofing job.

Step 1: Diagnose the problem

Use the table below. Clap once and listen for a ring, and notice whether bass booms or noise comes in from outside. Each problem has a different fix, so naming it first saves money.

Diagnose your room

  • Clap rings; words blur · Problem: Echo · Fix: Acoustic panels
  • Bass booms; notes uneven · Problem: Room modes · Fix: Bass traps
  • Bright, tiring sound · Problem: Harsh echoes · Fix: Panels on facing walls
  • Hearing neighbours/traffic · Problem: Leakage · Fix: Soundproofing

Step 2: Fix echo and harshness

Acoustic panels on the surfaces near people, one of each pair of facing walls, and the ceiling in big rooms. Aim to cover about 20–40% of the walls (20–40%). Spread panels out rather than grouping them on one wall. See where to place panels first.

Step 3: Fix boom

Bass traps in corners; thicker panels; better speaker and seat positions. Boom comes from low notes building up, mostly in small rooms. Standard panels alone do not fix it. See bass traps.

Step 4: Fix noise from outside

Panels will not fix this. Seal doors and gaps, fit solid doors and better windows, and close ceiling voids so walls run up to the slab. This is soundproofing, which is a different job from echo control. See treatment vs soundproofing.

Step 5: Add soft finishes

Rugs, curtains, upholstered furniture and full bookshelves help at the edges. They soak up a little echo, mostly at high notes. Most echoey rooms still need panels as well.

What we see on real jobs

A room can have more than one problem. Acqua E Farina on Keong Saik Road is pictured before treatment; after custom ceiling clouds and wall panels, guests talk without shouting. A home studio might have both echo and boom, needing panels and bass traps.
