Melaphone Speech Unit

Clear Communication. Improved Safety. No Power Required.

For over 60 years, the Melaphone Speech Unit has helped protect people during face-to-face communication.

Its proven design helps reduce the risk associated with airborne infection while maintaining clear, direct communication between speaker and listener.

But safety is only part of the story.

The unique tensioned membrane built into every air-sealed Melaphone Unit also amplifies speech, making conversations easier to hear and understand.

Up to 50% Sound Amplification

Recent laboratory testing has demonstrated up to 50% amplification of sound volume when a Melaphone is installed in:

• Glass
• Acrylic
• Wooden screens
• Single-glazed installations
• Double-glazed installations

This performance is supported by testing to ISO 14664-1 Class 5 and BS EN ISO 10140-2:2021.

The result is a simple yet highly effective communication solution that combines:

Greater safety • Improved sound clarity • Uninterrupted visual contact

An essential combination for successful face-to-face communication.

Simple, Hygienic & Maintenance-Free

The Melaphone is designed for straightforward installation in almost any surface, including brick, and requires:

• No wiring
• No power supply
• No electrical components

Available in two sizes and three finishes, including durable 316 stainless steel, the Melaphone is suitable for a wide range of environments.

Melaphone units can be safely and easily cleaned using antiseptic wipes and require virtually no maintenance.

Spare parts are available if ever required, although they are rarely needed.

With no electronics, wiring or complicated components, there is simply very little to go wrong.

Ideal for Cleanrooms & Controlled Environments

Melaphone Speech Units are now a popular choice in cleanrooms around the world, where clear and hygienic communication is essential.

They are particularly effective where communication takes place through sealed viewing windows, including:

• Double-glazed windows
• Thick walls up to 400 mm

The Melaphone provides clear communication while maintaining the physical separation required in controlled environments.
