K.R. Moeller Associates Ltd. has launched MODIO, a device specifically designed to address hotel noise. Using a sound similar to soft airflow, MODIO covers up intruding noises or reduces their disruptive impact by minimizing the amount of change between volume peaks and the guest room’s baseline background sound level. In the past, guests tried unsuccessfully to use the HVAC system, white noise apps or other gadgets in this manner. A commercial-grade masking system, like MODIO, properly generates sound, adjusts it via effective volume and frequency controls, and produces it over a high-quality loudspeaker. MODIO can be attached to the back of a TV, a wall or furnishing in minutes.
