Benefits of technology

This patent describes a new structure for an acoustic panel that can help reduce sound disturbance and create a more comfortable listening experience. The structure consists of a cavity enclosed by a continuous boundary wall, with a support structure arranged inside the cavity and a chamber suspended by the support structure. The chamber is closed on the entrance side and open on the floor side. The maximum cross-sectional areas of the floor side and entrance side of the chamber are designed to be about 0.5 and 10% of the cross-sectional area of the cell structure, respectively. This design helps create a more effective and precise sound absorption. The patent also describes a method for manufacturing this new structure using additive manufacturing techniques.

Problems solved by technology

However, technological challenges in manufacturing and material forming techniques often limit the amount of surface area available.

Abstract

An improved cell structure that enables design improvements to acoustic panels is provided. The provided cell structure for an acoustic panel is (i) capable of damping a wider range of audible frequencies, (ii) able to be easily combined and integrated into a variety of panel dimensions, and (iii) manufacturable using additive manufacturing techniques such as direct metal laser sintering (DMLS).

Description

TECHNICAL FIELD[0001]The present disclosure generally relates to acoustic panels and methods of producing the same, and more particularly relates to a cell structure for use in various acoustic panel applications, and methods of producing the same.CROSS-REFERENCE TO RELATED APPLICATIONS[0002]This Application is a continuation of and claims priority to U.S. patent application Ser. No. 15 / 702,414 filed Sep. 12, 2017, and entitled “CELL STRUCTURE FOR USE IN AN ACOUSTIC PANEL, AND METHODS OF PRODUCING THE SAME,” which is incorporated by reference in its entirety.BACKGROUND[0003]In a variety of applications, such as aircraft, aircraft engines, automotive, mining, farming, audio equipment, heating ventilation and air conditioning (HVAC), and the like, pressure waves are generated in a broad range of audible frequencies. The audible frequencies are sound waves experienced as noise. Acoustic treatments employ acoustic panels to dampen the sound waves.[0004]The performance of a given acousti...
