Description

Technical Field

[0001] This utility model relates to the field of soundproof sheds, specifically to a soundproof shed that eliminates low-frequency standing waves. Background Technology

[0002] Existing portable soundproof booths typically consist of a fixed frame assembled from multiple poles via connectors. The top and bottom of the fixed frame are equipped with end soundproofing pads, and multiple side soundproofing pads are arranged along the sides of the frame. Each side soundproofing pad has an entrance / exit for entry and exit, with a soundproof door at each entrance / exit that can be opened or closed. For ease of carrying and assembly, the assembled portable soundproof booth is usually a cuboid. Therefore, the end soundproofing pads and side soundproofing pads form a perpendicular angle, and the side soundproofing pads between adjacent surfaces also form a perpendicular angle. Sound inside the soundproof booth easily generates low-frequency standing waves at these angles. These low-frequency standing waves affect sound quality and pose a significant health hazard.
