Title: Innovations of John D. Lea
Introduction
John D. Lea is a notable inventor based in Huntington, NY (US), recognized for his contributions to acoustic technology. He holds a total of 5 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
One of his latest patents is the Controlled Compliance Acoustic Baffle. This invention is designed to reflect sound waves and reject background interference noise for use with a hydrophone array. The baffle incorporates a plurality of lenticular resilient elements embedded in a compliant foam elastomer compound. These elements control the overall baffle compliance for submarine applications, particularly under high hydrostatic pressure. The resilient members consist of pairs of lenticular shaped elements bonded to a highly damped constrained viscoelastic layer, ensuring uniform noise reduction performance across a broad frequency range. The design allows for free deflection up to a maximum operating depth, preventing excessive bending stresses.
Another significant patent is the Acoustic Particle Acceleration Sensor and Array of Such Sensors. This invention is responsive to acoustic particle acceleration, enabling the sensing of acoustic signals in regions of low acoustic pressure. The element can be isolated from acoustic noise when positioned near high acoustic impedance structures by utilizing a baffle that provides isolation from radiated and evanescent acoustic signals and structural vibrations.
