Sound-absorbing wall - Kyuonheki

Japanese: 吸音壁 - きゅうおんへき
Sound-absorbing wall - Kyuonheki

...By the way, a fire wall is a highly fire-resistant wall that can form a fire compartment to prevent the spread of fire within a building (however, it can also refer to a wall that is simply a fire-resistant structure), and a smoke barrier is usually a non-flammable soffit wall (smoke barrier) to prevent smoke from spreading along the ceiling. Other types of walls include soundproof walls (sound barriers) used around recording studios, etc., which are double-walled to increase sound insulation; sound-absorbing walls with uneven surfaces used in music halls to prevent echoes; heat-resistant and cold-resistant walls that use a lot of insulation material to block out the external thermal environment, such as around freezers; waterproof walls used in basements where high waterproofing is required (although as a general rule, all outer walls are required to be waterproof), storage walls such as partition walls that also have storage functions; radiation shield walls that are installed around rooms such as X-ray rooms where radiation is handled to block radiation; heat storage walls with a large heat capacity that extract solar heat and other heat over time; and light-transmitting walls that allow light to pass through like glass blocks but block most other factors.
[Load-bearing and non-load-bearing walls]
In addition to the walls that have the functions mentioned above, there are walls whose primary function is to support the building. These are called load-bearing walls or bearing walls.

*Some of the terminology that refers to "sound-absorbing walls" is listed below.

…ちなみに防火壁とは,建物内の延焼を防ぐための防火区画を形成しうる耐火性の高い壁をいい(ただし,単なる防火構造の壁を指すこともある),防煙壁は天井に沿って広がる煙を防ぐため,不燃性のたれ壁とする(防煙たれ壁)のがふつうである。こうした壁の種類としては,このほかに録音スタジオの周囲などに使われる壁で,二重壁などにして遮音性を高めた防音壁(遮音壁),音楽ホールなどで反響を防ぐために設けられる凹凸などを有する吸音壁,冷凍室の周囲など外部の温熱環境を遮断する目的で,断熱材を豊富に用いた防熱壁や防寒壁,高い防水性を要求される地下室などに用いられる防水壁(外周壁は原則としてすべて防水性が要求されるが,これは除く),間仕切壁などで収納の機能を一体としてもっている収納壁,レントゲン室など放射線を扱う室の周囲に放射線の遮断を目的に設けられる放射線シールド壁,太陽熱などを時間をおいてとり出すための熱容量の大きい蓄熱壁,ガラスブロックのように光は通すが,他のほとんどの因子は遮断する採光壁などがある。
[耐力壁と非耐力壁]
 以上述べたような機能をもった壁のほか,建物を支えるという機能を最優先する壁があり,これを耐力壁あるいはベアリングウォールbearing wallと呼ぶ。…
