Two-way radios are often used in challenging environments such as outdoor sites, industrial areas, and other noisy settings where machinery, wind, and traffic sounds interfere with clear voice communication. In such conditions, microphones must effectively reduce background noise and focus on the speaker’s voice. This typically requires a unidirectional design and a good signal-to-noise ratio to ensure voice clarity.
Furthermore, improper microphone sensitivity or limited frequency response can result in muffled sound or loss of voice details, especially when the speaker is not close to the microphone. It is crucial to balance sensitivity to prevent distortion from loud sounds while maintaining sufficient pickup. A frequency response that covers key human voice ranges (around 100Hz to 10kHz) is important to reproduce natural, clear audio.
Microphones also need to handle sudden loud noises without distortion; therefore, a high maximum sound pressure level (SPL), typically over 100dB, is necessary to maintain stability in emergencies or noisy bursts. Mechanical factors are also important since limited internal space demands precise microphone sizing and compatible pin configurations for secure soldering. This helps prevent poor contact caused by vibrations and ensures long-term reliability.
Offering standard sizes such as 6mm and 9.7mm for two-way radios, along with robust packaging and standardized pin layouts, supports easier integration and durability.
