Melaphone is specifically designed to allow sterile communication with a high degree of vision and safety. There is no thru-air flow, therefore, no transmission of germs, draughts or dust. Speech is transmitted through a transparent diaphragm which also gives protection against noxious sprays.


Hospital Room Windows

Are you looking to buy hospital talk through ticket windows? Melaphone is here to help. Our market-leading hospital speak holes are designed with a sterile, controlled environment in mind and they could be just what you need to ensure sterile day-to-day communication in your facility.

All of our hospital communication windows are constructed from a transparent polycarbonate diaphragm, with a wire mesh guard cover to the front. There is no thru air-flow and, as such, they successfully prevent the transmission of germs, contaminants and noxious spray. Yet, users can still benefit from a high degree of vision and can communicate easily with patients inside the room.

Hospital speak holes are very easy to install and, when purchased from us – here at Melaphone – you can rest assured, they have been built to strict ISO standards. If you would like to find out about Melaphones for use in a hospital, or any other industry, please feel free to get in touch. Either call us today on 01359 233191 or send an email to for more information.

Can germs pass through the Melaphone unit?

Due to the specific design of the unit, there is no thru-air flow. This means that germs, and other harmful contaminants, cannot pass through the unit.

How clear is communication using the unit?

The unit is designed to facilitate the mutual exchange of information. Thanks to its sensitive diaphragm, speech is clear and there’s no need for a loudspeaker or power supply.

Does the unit affect vision?

In short, no – the unit is constructed from clear polycarbonate and, as such, vision is not impaired. Even when installed in double glazing, a transparent cylinder is used to maintain visibility.

How easy are the units to clean?

The Melaphone is very easy to clean and maintain. They are resistant to wear and tear and, if a particular part needs to be replaced, we also offer a comprehensive range of spares.
