Acoustic advice for hotels: specialist in sleep comfort.
KGI Groep is the author of the NHR-ACOUSTICS-01:2025 (version 1.3), the international guideline for acoustic comfort and quiet in hotels. This makes us the specialist in hotel acoustics in the Benelux. We measure, assess and improve the acoustics of hotels based on objective performance requirements.
Schedule free consultationThe NHR guideline: two comfort classes
Class A (premium) is intended for boutique hotels and the higher segment. Class B (standard) offers a solid base level that every hotel can achieve. The guideline is product-neutral, performance-based and internationally applicable. Usable in specifications, brand standards, tender specifications and contract appendices. The guideline can be requested free of charge as a PDF.
What do we measure in hotels?
Sound insulation between rooms (room-room, room-corridor, room-plant room) compliant with NEN 5077 and NEN-EN-ISO 16283. Installation noise in the rooms (AC, ventilation, lift, water pipes). Façade insulation (traffic noise, environmental noise). Testing against NHR comfort classes. Based on the results we advise per problem area.
Quiet Room Label for your hotel
Hotels that meet NHR-ACOUSTICS-01:2025 receive the Quiet Room Label as proof of acoustic comfort. Usable for marketing towards guests, brand standards, hotel classifications and tender specifications. More and more hotel chains include acoustic requirements in their brand standards. We actively support the correct formulation of these requirements and the testing and certification of existing and new hotels.
Renovation and new-build guidance
For renovation or new-build of hotels we guide the acoustic process from design phase to post-measurement at handover. We review the specifications, calculate the expected sound insulation compliant with NEN-EN 12354 and flag risks before construction starts. This prevents costly adjustments afterwards and negative guest reviews after opening.
