The standard startup chime will automatically play when you turn on your Apple computer, open the lid of your newer MacBook Air or Pro, or restart it. It is a gentle reminder that the Mac is booting up and will be ready soon. But it might not be appropriate if your Mac is starting up in a peaceful setting like a library, classroom, or conference room. Turning off the Mac startup sound is simple on your subsequent boot. Using Terminal instructions, you can permanently turn off the startup sound on Mac or do so momentarily by adjusting the audio settings.
