调音量

Using it is very straightforward. You can use it as a verb phrase. For example, 帮我调一下音量 (help me adjust the volume). You can also add 大 (big) or 小 (small) to be specific. If you want it louder, say 调大音量. If it is too loud, say 调小音量. It is flexible and fits into most sentences easily. Don't worry about complex grammar here.

Use this in any tech-related situation. You are watching a movie with friends. You are in a Zoom meeting and can't hear. You are at a KTV and the music is blasting. It is perfect for asking a driver to turn down the radio. It works in both physical and digital spaces. If there is a speaker involved, this phrase is relevant.

Do not use this for people's voices. If your friend is shouting, don't say 调音量. Instead, say 小声点 (speak a bit quieter). It sounds robotic if used on humans. Also, avoid it in very high-level audio engineering. Professionals might use more technical terms like 增益 (gain). For everyday life, though, it is perfect. Keep it for devices and gadgets.

In China, public space noise is a common topic. You will often hear this in shared spaces. People are generally polite about asking to adjust volume. In high-speed trains, there are 'quiet carriages' now. You might see signs reminding you to 调低音量 (lower the volume). It reflects a modern urban etiquette of digital respect. It is a small phrase that shows big manners.

People often shorten it in casual speech. You might just hear 调大点 (make it bigger/louder). Or 调小点 (make it smaller/quieter). In technical settings, you might see 音量控制 (volume control). On a phone interface, it usually just says 音量. If you are feeling extra polite, add 请 (please) at the start. These variations make you sound much more natural.
