Do you have questions ?
The manager of Hotel Lion Borovets contacted us after a project we had done in his home. In winter, while parents ski, the children play with the entertainers in the hotel’s kids’ club. The noise from the games, however, did not stay in the kids’ club – it could be heard in some of the rooms and in the lobby bar and disturbed the other guests.
The task had two parts: to stop the noise reaching the other rooms and to reduce the echo in the kids’ club itself.
After the site visit we developed a two-part design:
The panels reduce echo in the room but do not stop noise to the adjacent rooms – that is why sound insulation is a separate part of the design. For reference: when a playroom borders bedrooms above or below it, Ordinance No. 4 of 2006 requires Rw ≥ 55 dB and L′nw ≤ 46 dB for the ceilings and floors. No measurement was made before and after the works.
Production took 5 working days and installation one. The project was completed in 2021. According to the hotel, the noise from the games no longer disturbs the other guests.
