80 Marine Parade Drive
With the conversions of a Yoga studio to an Auxiliary Gym Room, higher impact fitness activities were perceived in an adjacent tenant suite due to structure-borne noise, with measurements reaching 43 dBA contained in a frequency range of 80 to 160 Hz measured by the Acoustician.
Reported by the acoustician, the frequency response of the existing gym-floating floor installed at 80 Marine Parade Drive was measured in a heel drop test. The measured response frequency of the floor was broadly in a range centred at about 15 Hz.
CDM-CA Ltd designed, supplied and installed a retrofit floating floor solution. With use of past CDM lab test data, and by performing in-situ mock-up trials consisting of various material and cross-sectional designs, 3-different floor build-ups were tested, 1-remained as being 100% successful, resulting in no perceived vibration or audible noise in the tenant’s suite.
The CDM-FLOAT solution eliminated the 43 dBA measurements previously recorded, using a specific floor buildup not involving a concrete floating slab, to achieve a sound level of less than 35 dBA.
