Soundproofing acoustic booths: what you need to know before investing

Article published on 27 April 2026

Why soundproofing is crucial in open-plan offices

In modern workplaces, noise has become the leading cause of stress in the office, as revealed by several studies (JLL, INRS). The rise of hybrid working, video meetings and frequent phone calls exacerbates this noise overload. The result: concentration levels drop, fatigue increases, and confidential discussions become risky.

This is why soundproofing has become an essential criterion in office design. Before investing in an acoustic booth, it is essential to understand what guarantees effective and long-lasting sound insulation.

What is a well-soundproofed acoustic booth?

A well-soundproofed acoustic booth is designed to significantly prevent sound from entering or escaping. Sound absorption (which reduces echoes inside) should not be confused with sound insulation (which blocks noise between the inside and outside).

Effective soundproofing relies on:

  • High-density materials, carefully arranged,
  • A sealed, airtight structure,
  • A design tailored for professional use: calls, video conferences, HR interviews, confidential meetings…
