Abstract
A sound damping device includes an attachment portion, an engagement structure to engage a furring channel, and a shoulder disposed between the attachment portion and the engagement structure. The sound damping device has a spring rate of not greater than 12,000 kg/m. The sound damping device may be disposed between a support structure and a sheet material.
Claims15
A sound damping device comprising:
- an attachment portion that lies along a plane P1, has a central axis A perpendicular to the plane P1, and has a length L1;
- a shoulder that extends from the attachment portion out of the plane P1 at an oblique angle to a plane P2 and has a length L2;
- a wing that extends from the shoulder along the P2 to an end, has a length L3 in a first direction from the shoulder to the end, has a first portion near the shoulder, and has a second portion near the end, wherein the second portion is wider than the first portion in a second direction perpendicular to the first direction;
- and
- an engagement structure disposed on a major surface of the wing facing away from the plane P1, the engagement structure comprising opposing segments bent from opposing lateral edges of the second portion of the wing so as to extend out of the plane P2 in an axial direction relative to the central axis A away from the plane P1 so as to define a channel between the opposing segments and over the major surface of the wing facing away from the plane P1,
- wherein the wing is configured to flex in response to vibrations and to dissipate sound waves with a Transmission Loss Performance of at least 37 dB at 125 Hz;
- wherein a ratio of the length L3 to the length L1 is at least 1, and the length L3 is greater that the length L2, and
- wherein the sound damping device is formed of a single metal piece.

A structure comprising:
- a support;
- a sound damping device coupled to the support, the sound damping device comprising:
- an attachment portion that lies within a plane P, has an axis A perpendicular to the plane P, and has a length L1;
- a shoulder that extends from the attachment portion out of the plane P1 and has a length L2;
- a wing that extends from the shoulder along the plane P2 to an end, the wing extending from the shoulder at an angle β of not greater than 175° relative to the shoulder, and the wing having a length L3 in a first direction from the shoulder to the end, having a first portion near the shoulder, and having a second portion near the end, wherein the second portion is wider than the first portion in a second direction perpendicular to the first direction;
- and
- an engagement structure disposed on a major surface of the wing near facing away from the plane P1, the engagement structure compromising opposing segments bent from opposing lateral edges of the second portion of the wing and each of the segments extending out of the plane P2 in an axial direction relative to the central axis A away from the plane P1 so as to define a channel between the opposing segments and over the major surface of the wing facing away from the plane P1;
- wherein a ratio of the length L3 to the length L1 is at least 1, and the length L3 is greater than the length L2,
- wherein the sound damping device is formed of a single metal piece, and;
- a furring channel coupled to the engagement structure of the sound damping device;
- and
- a sheet material coupled to the furring channel,
- wherein the structure is adapted such that the wing can flex in a direction perpendicular to the plane P with a spring rate of not greater than 12,000 kg/m.
10 more elements
A sound damping device comprising:
- an attachment portion lying along a plane P and having a length L1;
- first and second shoulders disposed on opposite sides of the attachment portion within the plane and extending from the same surface of the plane P, the first and second shoulders each having a length L2;
- first and second wings extending from the first and second shoulders, in a first direction, to a first end and a second end respectively, in different directions substantially parallel to the plane P, each of the first and second wings having a length L3, and having a first portion near the first shoulder and the second shoulder, respectively, and having a second portion near the first end and the second end, respectively, wherein each second portion is wider than each first portion in a second direction perpendicular to the first direction
- first and second engagement structures disposed on a major surface of the first and second wings, respectively, facing away from the plane P, the first and second engagement structures adapted to receive a furring channel such that the wings can flex in response to vibrations and to dissipate sound waves with a Transmission Loss Performance of at least 63 dB at 800 Hz,
- wherein a ratio of the length L3 to the length L1 is at least 1, and the length L3 is greater than the length L2,
- wherein the sound damping device is formed of a single metal piece.
