    摘要： In one embodiment, a system for monitoring exposure to impulse noise includes a sound-sensing device, such as a microphone or other type of pressure transducer, operable to sense impulse noise, and a storage module operable to store the waveform of the impulse noise sensed by the sound-sensing device. The sound-sensing device desirably is operable to sense impulses that are greater than 146 dB, such as impulses created by construction machinery and firearms. The system also can include a processor operable to calculate one or more noise parameters of the impulse noise from the waveform, and a user interface program operable to display said one or more noise parameters selected by a user.

    摘要： A method for monitoring exposure time of workers involves the use of a sensor, which is carried by the workers for monitoring continually in a real-time fashion in an environment such that the results are recorded by a recorder. The an add-on or built-in timer in the sensor or the recorder is used to monitor time, which is recorded in the recorder simultaneously, so as to obtain the real-time continuous exposure level of a hazardous material in the environment.

    摘要： A system for monitoring the level of an intelligence-containing audio frequency signal wherein an operator audibly monitors the signal but cannot adequately monitor a visual level indicator. The system utilizes a threshold detector which compares the level of an audio frequency signal to a preselected level and generates a control signal if the audio frequency signal exceeds the threshold. The system further includes a gate which couples a tone to the headphones of the operator in response to generation of the control signal. In an alternative embodiment, if a second threshold is exceeded, the threshold detector generates a second control signal which changes the tone signal frequency.

    摘要： A sound level alarm device sequentially listens to the sound level of an enclosure or area for a first predetermined interval of time, and thereafter does not listen to the sound level of the area for another predetermined interval of time. The circuit sounds an alarm upon detection of a sound level of a predetermined magnitude measured during the first time interval. The circuitry is designed for omitting quick, sharp noises such as a cough, hand clap, book dropping, or the like. The apparatus is advantageously used in class rooms, laboratories, libraries, and play rooms as a teaching aid wherein people with loud noisy habits are electronically assisted in overcoming these undesirable aspects of their life style.

    摘要： An apparatus for obtaining the farfield directional pressure intensity of a sonorous source placed in a fluid medium from pressure measurements taken in the nearfield of the source is disclosed. An acoustic antenna is placed in the nearfield of the source to map the acoustic pressure nearfield. The antenna consists of either a single receptor, or of two separate receptors, one fixed in position to define the direction and the other variable in position over the acoustic antenna. Each receptor is comprised of two oppositely facing parallel planar arrays of acoustic detectors separated by a predetermined distance. The detectors are arranged in each array in a predetermined matrix. The detector signals from both arrays are processed by either of two different methods, an additive or a multiplicative method, to obtain the farfield directional pressure intensity of the source.
