Check out the example given here. From 00:00 to 01:15 – the original recording is easy-pop tempo (125 bpm) of medium intensity, smooth, and not heavy.
In the remix, from 01:15 to 02:21, the production is raised to high-intensity; the tempo is the same (125 bpm), the volume is the same, but it sounds louder. It is perfect for bars.
In a typical ‘front desk + lounge-bar + restaurant’ open area, the medium-intensity sound will enable a conversation in the restaurant while keeping up the bar’s atmosphere, without disturbing the front desk area.
Pumping up the volume of a low-intensity recording will disturb the conversation in the restaurant and affect the front desk.
