1、河北省2026届重点高中高三检测试题(11月)数学试题
【答案】C
【知识点】声音的产生；声音的传播条件；超声波与次声波；音调、响度与音色的区分
【解析】【解答】人的听觉范围是20Hz～20000Hz，狗的听觉范围是15Hz～50000Hz，人什么也没听见，是因为驱狗器发出声波的频率不在人耳能够感受的频率范围内，而在狗的听觉范围之内，所以对着狗一按开关，狗好像听到巨大的噪声而躲开，而旁边的人什么也没听见，故C正确，ABD错误。故选C。
【分析】 超声波是指高于20000Hz的声音，次声波是指低于20Hz的声音。人耳无法听到超声和次声。人的听觉范围是20Hz～20000Hz，狗的听觉范围是15Hz～50000Hz。
7．（2024八上·岳阳期中）下列有关声音的特性，说法正确的是（ ）
A．甲图中钢尺伸出桌面长度越长，拨动它时发出的声音的音调越高
B．乙图中用相同大小的力敲击不同水量的瓶子，从左到右音调变低
