What is the acoustic rating required for a 5-star hotel?



How to choose 5 things to check acoustic materials perfectly?

: walls with sound insulation performance standards using STC (Sound Transmission Class) as a reliable metric for acoustic design. Specifically, meeting the Industry Benchmark widely accepted today, standard walls typically provide an STC rating around 50 while premium walls can achieve STC 55 (laboratory tests reach 58-60). This effectively prevents sound from penetrating between rooms, unlike general partition walls built with standard materials which usually yield only STC 36-44, leading to sound leakage issues. In contrast, high-performance acoustic wall systems like Trandar Hitech Wall (TSIS) can achieve up to STC 58 with a total wall thickness of just 10.5 cm.

STC Rating Guide for Walls

• The STC (Sound Transmission Class) rating is an integer rating of how well a building partition attenuates airborne sound. From ordinary speech to loud noises, an STC 50 wall will generally block most loud speech, whereas an STC 55 wall allows almost no loud speech to be heard. However, higher STC ratings do not necessarily solve low-frequency impact noise issues, such as heavy footfalls.

Standard STC Wall Rating Guidelines

Standard building codes usually require a minimum STC rating for partition walls to ensure basic acoustic comfort and privacy between rooms.

• Soundproofing interior walls with a 5-layer system offers superior acoustic performance compared to standard single-wall installations, effectively blocking out noise from adjacent rooms and enhancing privacy.
• High sound transmission loss with exceptional STC ratings providing top-tier acoustic insulation for residential and commercial buildings. Soundproof walls (drywall partition systems) significantly reduce airborne noise and improve overall acoustic comfort, providing peace and quiet for every room.

How to soundproof a wall with a 5-layer system

Standard partition walls are typically only about 10 cm thick. However, STC soundproof walls vary by model; for instance, STC 36 is suitable for general partitioning, while STC 42 offers moderate sound blocking, and STC 50-55 systems—which are 4-5 cm thicker—provide exceptional acoustic performance. Choosing the right STC rating depends on the specific noise control requirements of each room, such as meeting rooms or bedrooms, ensuring maximum privacy and minimal disturbance.
