In modern healthcare environments, an efficient intercom system is essential for seamless communication between medical staff. Whether for remote calls between the nurse station and patient rooms or emergency call systems in surgical and intensive care units, clear and stable audio transmission significantly improves workflow efficiency and ensures patient safety.
Key Factors Affecting Pickup Distance and Transmission Quality
1. Microphone Pickup Sensitivity
The sensitivity of a microphone directly impacts the sound pickup distance and clarity. Higher sensitivity microphones can capture audio from a greater distance, providing an enhanced communication experience in quiet environments.
2. Product Structure and Acoustic Design
The enclosure design, microphone placement, and echo cancellation technology all contribute to overall performance. Proper sealing and anti-vibration design help reduce background noise and ensure stable sound pickup.
3. Amplifier Circuit and Signal Processing
Without an amplifier circuit, the typical pickup range is about 1-2 meters. However, integrating an amplifier circuit with the right gain can extend the pickup distance to 5 meters or more, depending on the system’s specific requirements.
Recommended Microphone Solutions for Hospital Intercom Systems
For long-distance pickup in environments like nurse stations, ICU rooms, and remote call systems, the ECM-B9745AL30RC microphone is an excellent choice. With a sensitivity of -30dB±2, it ensures clear sound pickup even from a distance. Its omnidirectional directivity and 2.2KΩ impedance make it highly effective in environments where sound clarity is crucial. This model offers a S/N ratio of 74dB and can handle a maximum SPL of 110dB. With an operating voltage of 2Vdc and a frequency response from 50Hz to 20KHz, it provides reliable performance in demanding hospital settings.
