Key benefits of our noise cancelling intercom system for medical facilities
Our noise-eliminating intercom solutions leverage state-of-the-art DSP technology to:
- Reduce unwanted noise by up to 98%
- Maintain optimal speech clarity in high-noise environments (60-80dB)
- Ensure seamless integration with existing medical equipment
- Provide medical-grade reliability for critical communications
Enhanced patient experience
Our healthcare intercom system significantly reduces patient anxiety and stress by ensuring clear, continuous communication in healthcare environments during medical procedures. Patients can be clearly understood and receive reassurance and instructions from clinical staff with clarity, even in enclosed or noise-intensive areas.
Improved clinical efficiency
Healthcare professionals benefit from the following:
- Immediate, clear communication without repetition
- Reduced vocal strain and listener fatigue
- Enhanced procedure coordination
- Improved workflow efficiency
- Decreased risk of miscommunication

Top bhi communication systems for healthcare facilities
NEIS-RM25
- Advanced adaptive noise cancelling DSP technology
- Compatible with major radiotherapy and CT equipment
- Modular system for easy retrofitting with existing machines
- Flexible installation options
- Medical-grade build quality
- Comprehensive noise elimination capability
The bhi NEIS-RM25 leverages cutting-edge Digital Signal Processing (DSP) technology to facilitate intelligible speech from within noisy environments. Proprietary algorithms analyse incoming audio to identify speech signals and filter out interfering background noise in real-time. This reduces distracting machine and ambient sounds by up to 98%, leaving only the clear voice signal.
With robust desktop stations and sleek speaker units, bhi intercoms integrate seamlessly into any medical workspace. The modular design allows flexible positioning of microphones near patients. Simple CAT5 cabling enables rapid installation in imaging suites or radiation bunkers without too much disruption.
NEDSP1901 Low-Level Audio Modules
- Retrofit modules which optimise speech clarity in medical settings
- 40dB noise reduction filters out machinery and equipment sounds
- Compact design with low power use and flexible integration
- Adjustable controls for optimal noise cancellation
- Real-time processing ensures clear two-way communication
The NEDSP1901 provides exceptional noise reduction of up to 40dB across the key 300Hz to 5KHz speech bandwidth. This allows voices to cut through loud machinery rumble, patient monitoring beeps, and other interfering hospital sounds.
With its low power draw and compact profile, the NEDSP1901 seamlessly integrates into space-constrained medical equipment in either the receive audio path or microphone path. Flexible control options allow developers to optimise noise cancellation while minimising power usage.
By eliminating unwanted noise and interference at the signal level, the NEDSP1901 delivers the crisp, intelligible two-way communication essential for patient care and safety.
