The Whispering Window emits music or messages through a window, creating aunique way to deliver sales and marketing messages throughout your store.

Shopping experience audio in window

Unlike regular speakers, using Whispering Window won’t obstruct the view into your store. And because the sound is evenly distributed throughout the surface, you won’t have to crank it up to annoying levels – customers will be able to hear your messages while still being able to carry on a conversation and have a pleasant shopping experience. Whispering Window sound is passive but it provides an aggressive marketing tool.

Technology of whispering window

Whispering Window sound drivers are small and unobtrusive. Utilizing a patented process, two transducers easily bond to any glass pane and attach to an included amplifier, which can work from any sound source. Noise pollution is controlled by a real time feedback that ensures the window never ‘whispers’ above a small amount over the outside noise level. The unique properties of this technology means only people on the pavement directly in front of the window hear the message. The transducers – chrome finished and the size of a hockey puck – go unnoticed and are easily hidden with minimal décor.


Whispering Window has been used many times as part of in-store marketing programs to increase footfall and sales with great results.

Use Whispering Window to:

  • Build brand and image awareness
  • Drive traffic into your store or restaurant
  • Accompany signage or other visual elements
  • Increase sales of a specific item or area within your location

Glass Speakers – Turn Surfaces into Vibration Speakers

A Feonic Vibration Speaker will work on a wide range of resonant surfaces in addition to glass windows : Plexiglas, wooden floors, metal, drywall walls and ceilings and so on. Even a shipping container can be transformed in sound

The use of audio in outdoor advertising has been limited by the inability of conventional loudspeaker technology to meet the stringent environmental demands of both the quality and control of sound. ‘Whispering’ Windows uses GLIMM technology to deliver subtle, effective and controlled sound when used in outdoor advertising or as part of a retail display campaign.
Glimm ability to convert all sorts of smooth, hard surfaces as well as windows into loudspeakers represents a paradigm shift for the outdoor and in-store media industry
