Golden Ear 24, a proprietary system by IMS SA is intended to keep the volume and quality of broadcasted advertising content at an appropriate level. This method is one of its kind – it is based on constant volume control, depending on the acoustic conditions at a point of sale.

Permanent on-line control significantly increases the level of quality connected with trouble-free operation – all irregularities are monitored and, if necessary, immediately reported. As the system is calibrated, it can be used both by individual and network clients, in multi-zone large-format facilities and smaller facilities with smaller requirements.
