CitizenM Hotel, Bride Street

The Dublin St. Patrick’s Hotel is a city-centre modular hotel development requiring a comprehensive acoustic design to provide appropriate levels of guest comfort, control external environmental noise and achieve suitable sound insulation between bedrooms and other occupied spaces. A key consideration was ensuring that the modular construction system could achieve the required acoustic performance while remaining practical for off-site manufacture and on-site assembly.

Allegro Acoustics provided acoustic consultancy throughout the design stage, beginning with baseline environmental noise monitoring to establish the existing acoustic environment. A detailed 3D environmental noise model was developed using SoundPLAN to assess noise from the surrounding road network and external building services plant. The modelling was used to inform the façade design and establish the acoustic performance required to achieve suitable internal noise levels within guest bedrooms.

Detailed acoustic design criteria were developed for façade sound insulation, internal walls and floors, doors, reverberation control, building services and external plant. Particular consideration was given to the acoustic performance of the modular wall and floor constructions, with practical recommendations and façade mark-ups provided to integrate the required acoustic performance into the modular building system.

The acoustic consultancy provided the project team with a robust framework for the detailed design of the hotel, addressing the specific acoustic challenges associated with modular construction while helping create comfortable guest environments with appropriate control of external noise, sound transfer between spaces and building services noise.
