摘要： Systems and methods for measuring noise exposure associated with use of a wireless headset are presented. In one example, a transition from a wireless headset standby mode operation to a wireless headset active mode operation is identified. A stored noise dose measurement at the wireless headset is recalled, and a current noise dose measurement is calculated at the wireless headset for a duration of the active mode operation. A transition from the wireless headset active mode operation to the wireless headset standby mode operation is identified, and an updated noise dose measurement is recorded at the wireless headset.

摘要： An improved boom adapted for use in or with a headset is disclosed. The boom generally comprises a voice tube having a first entry aperture, a light tube, and a noise reducer. The noise reducer is composed at least partially of a porous plastic material and partially or fully covers the voice tube, the noise canceling tube, and/or the light tube.

摘要： Sound pressure level limiter with anti-startle feature for audio systems are disclosed. The anti-startle feature may be implemented with a delta incident detector for detecting delta acoustic incidents that exceed a predetermined acoustic startle boundary, a delta limiter for determining an anti-startle gain, and an amplifier to apply the anti-startle gain to the input signal. The delta incident detector may detect delta incidents based on an estimated true SPL delivered by a transducer to a predetermined datum point. The estimated true SPL may be determined by based on a measured receiving frequency response of the transducer. An SPL limiter may also determine an SPL gain in response to detecting an SPL acoustic incident that exceeds a predetermined SPL threshold, and an amplifier may apply the SPL gain to the input signal to reduce it below the threshold.
摘要翻译：公开了具有用于音频系统的防惊吓功能的声压级限制器。抗惊吓特征可以用用于检测超过预定的声音惊奇边界的三角洲声学事件的增量入射检测器来实现，用于确定防惊吓增益的增量限制器，以及用于将抗惊吓增益应用到输入端的放大器信号。 δ事件检测器可以基于由换能器传递到预定基准点的估计的真实SPL来检测δ事件。估计的真实SPL可以通过基于所测量的换能器的接收频率响应来确定。响应于检测到超过预定SPL阈值的SPL声学入射，SPL限制器还可以确定SPL增益，并且放大器可以将SPL增益应用于输入信号以将其降低到阈值以下。
