Definition

1. Adjective:
   • Impossible to hear; imperceptible by the ear: Describes a sound that is so quiet or faint that it cannot be detected by the human sense of hearing.

Usage

The word "inaudible" is used to describe sounds, whispers, noises, or speech that lack sufficient volume or clarity to be heard. It is often used in contexts involving acoustics, communication, or observation. - It typically follows a linking verb like "was," "is," or "became" (e.g., "The sound was inaudible."). - It can be placed before a noun it modifies (e.g., "an inaudible whisper").

Examples

• The dog whistle produced an inaudible high-frequency sound for humans.
• Her muttered apology was almost inaudible over the noise of the crowd.
• Due to the faulty microphone, the speaker's voice was inaudible to the audience in the back rows.

Advanced Usage

• "inaudible to": Used to specify who or what cannot hear the sound.

• In literary or descriptive writing, "inaudible" can describe metaphorical sounds or a profound silence.
