Also the positioning of the speakers in every interactive playset ensure that the players can hear the sound optimally, whereas the neighbourhood experiences as little disturbance as possible.
For example, to prevent sound to carry far, the Yalp Fono Dj booth is designed with sides of concrete and speakers directed inwards, to keep sound mainly focused at the DJ playing the Fono, and the near audience. The minimum sound level of the Fono in use is around 60dB (same as a normal conversation). The maximum sound level of the Sona in use is around 95 dB (same as a high volume stereo). As a rule of thumb, we advise not to place the Fono within 50 meters of the nearest residence.
