Abstract
(EN)
[Problem] To provide an automobile sound insulation panel suitable for reducing the weight of the sound insulation panel, expanding a frequency band where sound insulation is possible, and improving sound insulation performance. [Solution] This automobile sound insulation panel SI has a structure in which: an elastic sheet material 3 is located between a first panel material 1 and a second panel material 2; the elastic sheet material 3 has a first protruding and recessed portion 4 and the first panel material 1 is in contact with the top opening edges of a plurality of recesses 4A that constitute the first protruding and recessed portion 4; and separate air layers AG1 exist between the second panel material 2 and the elastic sheet material 3, and a continuous air layer AG2 exists between the first panel material 1 and the elastic sheet material 3.
