摘要： Systems and methods for monitoring a sound pressure level dose at an ear are provided. A system includes an audio transducer which outputs a sound signal is placed within an ear to receive sound at the ear. A sound level threshold detector determines whether a sound pressure level of the sound signal is at a minimum level and outputs a sound pressure level signal corresponding to the sound pressure level when the sound pressure level is not at the minimum level. A time period is calculated during which the sound pressure level is not at the minimum threshold level. A listening fatigue calculator determines whether a cumulative effect of exposure to the sound signal at the ear over the time period will cause harm to the ear. At least a portion of the system is disposed in situ at the ear.

摘要： A sound signal output apparatus includes: a wearing state determination unit which determines whether or not a connected speaker apparatus is fitted to an ear of a user; a volume adjustment unit which adjusts volume of a sound signal to be supplied to the speaker apparatus; and an accumulative computation unit which computes an accumulative value of output volume in accordance with a volume level and sound output time of the sound signal, causes the volume adjustment unit to execute volume regulation when the accumulative value reaches a regulatory value, and does not compute the accumulative value during a period in which the wearing state determination unit determines that the speaker apparatus is not fitted to the ear.

摘要： Methods of acoustic dose monitoring and acoustic dose systems are provided. An acoustic dose system includes a first device configured to measure sound pressure levels directed to an ear drum and a second device configured to convert the sound pressure levels into a sound pressure level dose. The second device sends a notification signal to a third device if the sound pressure level dose is larger than a threshold value.

摘要： A method for monitoring and reporting sound pressure level exposure for a user of a first communication device (104) is implemented in one embodiment when the device measures a sound pressure level (SPL) of the surrounding environment. The device stores at least the SPL measurement in a memory, producing an SPL exposure record, and displays a visual representation of the SPL exposure record on a display screen (212). In another embodiment, the SPL is measured by a second communication device (102) and combined with a known SPL for an output audio transducer (306) of the second device, producing a user sound exposure level. The user sound exposure level is transmitted to the first communication device. The user is notified when the user sound exposure level exceeds a predetermined threshold. A server (112) may also be used to track SPLs over time and recommend corrective action when exposure limits are exceeded.

摘要： A device to measure or to estimate the acoustical output of the loudspeaker of a earphone, earplug, headphone or ear muff, and to measure the ambient environmental sounds where appropriate. The loudspeaker is connected to an electronic audio device. The acoustical output of the loudspeaker may be measured by means of a microphone placed in close proximity to the loudspeaker; or estimated by means of measuring the output of the audio amplifier (in the electronic audio device) and using the output/input transfer function that relates the acoustical output of the loudspeaker to the output of the audio amplifier; or estimated by means of the output the digital signal processor (in the electronic audio device) and using the output/input transfer function that relates the acoustical output of the loudspeaker to the output of the digital signal processor. The measurement or estimation of the acoustical output of the loudspeaker (and measurement of the ambient environmental noise, if appropriate) may be used to realize a noise dosimeter or as a means to determine the maximum allowable output limit of the electronic audio device.

摘要： A personal noise dosimeter having functionality for increasing the dynamic range of the device. A microphone provides a signal to an RMS detector, which provides a DC signal to a two-stage amplifier circuit. The outputs of the amplifiers are provided to a processor having multiple A/D channels. The processor calculates accumulated noise doses and drives a display, which in one embodiment includes a panel of light-emitting diodes. A current source injects current into the output of the RMS detector to reduce performance degradation. Functionality detects and accounts for voltage offsets in the dosimeter. The microphone is turned off during offset determination. In one embodiment, the dosimeter includes functionality for control of external devices such as sound boards.
