A sound-absorbing mask is configured for covering a mouth. The sound-absorbing mask includes a covering body, a ventilation structure and a sound-absorbing portion. The covering body has a first chamber, a first and a second openings. The first chamber communicates with the first and the second openings. The first opening corresponds to the mouth. The ventilation structure is disposed at the second opening and has a second chamber, a third and a fourth openings. The second chamber communicates with the third and the fourth openings. The fourth opening is away from the first opening. The ventilation structure includes a plate disposed in the second chamber. The plate has a functioning surface facing the third opening. An edge of the plate and an inner wall of the ventilation structure have a gap in between. The sound-absorbing portion is disposed between the ventilation structure and the first opening.

Apparatus and methods include a single-pair earphone sterilize with germicidal light. Embodiments include a housing and a germicidal light source. The apparatus may include circuitry, such as power, to support the germicidal light source and a divider to shield the circuitry from the germicidal light source. The apparatus may also include attachment portions to position and maintain earphones in a position relative to the germicidal light source.
