一:分贝是什么意思(中英文)解释的意思
分贝是一个用来衡量声音强度的单位,它可以用来表示声音的大小和高低。它通常用于测量噪音、音乐或其他声音的强度,并且可以帮助人们更好地了解和周围的声音环境。
Decibel is a unit used to measure the intensity of sound, which can be used to indicate the loudness and pitch of a sound. It is commonly used to measure the intensity of noise, music or other sounds, and can help people better understand and control their surrounding sound environment.
分贝读作[fen-bei],其中“fen”发[fən],“bei”发[beɪ]。
Decibel is pronounced as [fen-bei], with "fen" pronounced as [fən] and "bei" pronounced as [beɪ].
分贝通常作为一个名词使用,它可以单独使用或者与其他词组合在一起。它也可以作为动词使用,表示测量某个声音的强度。
Decibel is usually used as a noun, it can be used alone or combined with other words. It can also be used as a verb to measure the intensity of a sound.
