Patent number: 10264999Abstract: Systems, apparatus, and methods for collecting, interpreting, and utilizing noise exposure data may include sensors to obtain an analog signal representative of impulse noise sound pressure and an analog signal representative of continuous noise sound pressure. At least one ADC may generate digital signals by sampling the analog signals at rates equal to or greater than twice the reciprocal of a minimum impulse noise rise time. Accelerometers may obtain data in close proximity to and remote from the sensors. At least one processor may include a first combining node to combine the digital signals to represent both the continuous noise and the impulse noise, a shock-artifact detection filter to identify a time frame including a shock artifact based on the accelerometry data, a frequency filter to generate a background-removed audio signal, an adaptive filter to estimate the shock artifact, and a second combining node to produce a shock-artifact-free audio signal.Type: GrantFiled: January 5, 2018Date of Patent: April 23, 2019Assignee: Massachusetts Institute of TechnologyInventors: Joseph J. Lacirignola, Trina Rae Vian, Christopher J. Smalt, David F. Aubin, Jr., David C. Maurer, Mary Katherine Byrd, Christine M. Weston, Kerry A. Johnson, Shakti Davis, Olha Townsend, Paul T.

Patent number: 10225672Abstract: Loud sounds with fast rise times, like gunfire and explosions, can cause noise-induced hearing loss (NIHL). Unfortunately, current models do not adequately explain how impulsive sounds cause NIHL, which makes it difficult to predict and prevent NIHL on battlefields and other hostile or rugged environments. Fortunately, the impulsive sounds experienced by soldiers and others working in rugged environments can be recorded using a compact, portable system that acquires, digitizes, and stores high-bandwidth audio data. An example of this system can be mounted on a helmet or other article and used to record hours of audio data at a bandwidth of 20 kHz or higher, which is broad enough to capture sounds with rise times less than 50 ms. An analog-to-digital converter (ADC) digitizes these broadband audio signals at rate of 40 kHz or higher to preserve the impulse information. A processor transfers the digitized samples from a buffer to a memory card for later retrieval using an interrupt-driven processing technique.Type: GrantFiled: April 17, 2018Date of Patent: March 5, 2019Assignee: Massachusetts Institute of TechnologyInventors: Joseph J. Lacirignola, Trina Rae Vian, David F. Aubin, Jr., Thomas F. Quatieri, Kate D. Fischl, Paula P. Collins, Christopher J. Smalt, Paul D. Gatewood, Nicolas Malyska, David C. Maurer

Patent number: 9254500Abstract: A feed aerosol comprising detectable particles is injected into a mix-enhancing swirler. Diluting gas is also injected into the mix-enhancing swirler and mixed with the feed aerosol in a swirling motion to form an aerosol with a particle concentration no greater than 1,000 particles per liter. The aerosol is then injected into a mixing chamber, where the aerosol is mixed and dried; the inner diameter of the mixing chamber is at least twice as great as that of the swirl chamber. The aerosol is then emitted through a flow straightener that removes swirl from the flow of the aerosol and passed through a delivery conduit, where the particles are detected and counted; and the particle count is compared with a target count. The respective flows of feed aerosol and diluting gas can then be increased or decreased based on a comparison of the particle count with the target count.Type: GrantFiled: October 9, 2014Date of Patent: February 9, 2016Assignees: Massachusetts Institute of Technology, The United States of America, as represented by the Secretary of the NavyInventors: Jesse Allen Linnell, Trina Rae Vian, Joseph Renard Morency, Anlong Dai, Mark Eric Bury, Thomas Sebastian, Carlos Andres Aguilar, Joseph John Lacirignola, Jay D.
