Lucky Voice is a Tokyo inspired chain of karaoke clubs that allows friends to hire private booths by the hour. The club's Soho branch wished to make an application to extend their licensing hours. RBA were appointed to undertake a detailed acoustic assessment which was required for the application as the venue is situated in Westminster City Council’s Central Activity Zone and Stress Area.
Due to the activity at the venue the building fabric been designed so that there is no audible noise break-out from the venue itself. RBA's assessment was therefore required to consider noise from patrons leaving the venue and from the mechanical plant serving the premises.
Initially an environmental noise survey was undertaken directly outside and within the vicinity of the karaoke bar to establish the local noise climate. In conjunction with Lucky Voice staff, a survey was also conducted of patrons exiting the bar to ascertain their movements up and down Poland Street and also the number of people that left via taxis. The acoustic assessment of the mechanical plant serving the bar indicated 24 hour operation would be acceptable due to the distance and screening afforded to the nearest residences.
The results of both assessments indicated only a marginal increase in noise would be expected as a result of extended opening hours.
