Close-talk handheld microphone is designed for communication systems, mobile and fixed station, including police, fire, utilities, transportation, commercial and industrial applications. Suitable for environments with high levels of background noise. For proper operation, mouth-to-microphone distance should be 1-inch (2.5cm) or less. It can be used in all types of mobile communications, from amateur radio to helicopter news and traffic reports. It is also suitable for public address and paging systems in noisy areas such as factories, airport terminals and restaurants. It represents significant improvement over most microphones with anti-noise features. Shaped frequency response, directionality and distant sound discrimination contribute to total noise reduction. Microphone operates on pressure-gradient principle and has two sound entry ports spaced small distance apart.
