过度暴露在高水平的噪音中会导致永久性听力障碍，对受影响者的生活质量产生重大不利影响。噪音造成的伤害会影响到各行各业的人，包括建筑工人、工厂工人和武装部队成员。通过监测工人的噪音暴露，可以避免过度暴露，并提供适当的防护设备。这项工作的重点是创造一种适合武装部队成员使用的噪声剂量计，其中离散剂量计被集成到纺织头盔罩中。通过这种方式，传感元件可以非常接近耳朵，提供进入人体的声级的高度代表性指示，并创造出一种不会干扰军事活动的装置。这是通过利用集成在纱线纤维中的商用微电子机械系统麦克风来制造声学传感纱线来实现的。在纱线生产过程的每个阶段，声波传感纱线在一系列相关的声级和频率上进行了充分的表征。这些纱线最终被整合到针织头盔罩中，创建了一个功能强大的声学传感头盔罩原型。
Overexposure to high levels of noise can cause permanent hearing disorders, which have a significant adverse effect on the quality of life of those affected. Injury due to noise can affect people in a variety of careers including construction workers, factory workers, and members of the armed forces. By monitoring the noise exposure of workers, overexposure can be avoided and suitable protective equipment can be provided. This work focused on the creation of a noise dosimeter suitable for use by members of the armed forces, where a discrete dosimeter was integrated into a textile helmet cover. In this way the sensing elements could be incorporated very close to the ears, providing a highly representative indication of the sound level entering the body, and also creating a device that would not interfere with military activities. This was achieved by utilising commercial microelectromechanical system microphones integrated within the fibres of yarn to create an acoustic sensing yarn. The acoustic sensing yarns were fully characterised over a range of relevant sound levels and frequencies at each stage in the yarn production process. The yarns were ultimately integrated into a knitted helmet cover to create a functional acoustic sensing helmet cover prototype.
