Antonyms for Spontaneous Otoacoustic Emission (SOAE), which refers to the unexplained sounds produced by the inner ear, include silence, quiet, stillness, and absence of sound. While SOAEs are a normal occurrence in healthy individuals, their absence may indicate hearing damage or deafness. Other antonyms, such as artificial or induced emissions, refer to situations where sound is intentionally produced or manipulated, as opposed to the natural, unexplained sounds of SOAEs. Seeking medical attention is advised for those experiencing hearing loss or the absence of SOAEs, as it may indicate underlying health concerns.
