Without a sound means to be completely silent or to make no noise whatsoever. It can refer to a lack of audible disturbance, where there is an absence of any auditory sensation or vibration. This phrase is often used to describe a situation or action that happens without making any noticeable or perceptible sound.
When something occurs without a sound, it means that there is no audible indication or indication of its happening. For example, a ghostly figure gliding through the room without a sound implies that there was no noise accompanying their movement. Similarly, a cat sneaking up on its prey without a sound suggests that it has approached silently and undetectably.
This phrase can also describe a lack of sound production from an object. For instance, a car engine starting without a sound suggests that the engine is running smoothly and quietly. Likewise, a door closing without a sound implies that it was closed gently and without any noise.
In a broader context, to say that someone vanishes or disappears without a sound suggests that their departure went unnoticed and without any audible indication. Without a sound indicates a complete absence of noise or a motion happening silently and discreetly, leaving little or no trace of its occurrence.
