"管乐器或汽笛声" can be translated as "the sound of wind instruments or whistles" in English. Here, "wind instruments" refers to musical instruments played by blowing air into them, such as flutes, trumpets, etc., while "whistles" typically denote the high-pitched sound produced by a whistle device, often used in signaling or as a warning. This translation captures the essence of the original Chinese phrase, encompassing both musical instruments and a specific type of sound-producing device.
