The phrase "capable of being heard" is commonly used to describe sounds that can be perceived by the human ear. Phonetic transcription using the International Phonetic Alphabet (IPA) would reveal that "capable" is spelled /ˈkeɪpəbəl/, with stress on the first syllable and a final syllable pronounced with a schwa sound. "Being" is spelled /ˈbiːɪŋ/ with stress on the first syllable and the second syllable pronounced with a short "i" sound, while "heard" is spelled /hɜːrd/ with stress on the first syllable and a final syllable pronounced with a soft "r" sound.
Capable of being heard refers to the quality or characteristic of a sound or voice that can be perceived or detected by the human ear or other auditory senses. It implies the potential for sound waves or vibrations to reach the ears and be interpreted as audible noise.
In practical terms, something that is capable of being heard can be heard at a certain volume or distance without the need for amplification or special devices. It means that the sound is not too faint, muffled, or distant to be discernible to the average person.
This concept of audibility may vary depending on the context. For instance, in legal contexts, it may refer to the requirement that certain communications or warnings be clearly heard and understood. In this sense, being capable of being heard implies that the information or message is conveyed effectively and comprehensibly.
In addition, the notion of being capable of being heard provides a framework for evaluating the qualities that make sound or voice audible. These include factors such as volume, frequency, pitch, and clarity. If a sound possesses these qualities to a sufficient degree, it can be considered capable of being heard.
