High-frequency hearing loss among mobile phone users.
This prospective single-blinded study assessed hearing above 8 kHz among prolonged mobile phone users using high-frequency audiometry. Because few non-users were available, the study compared each participant’s dominant (phone-used) ear with the non-dominant ear, with the audiologist blinded to dominance. The authors report significantly greater high-frequency hearing loss in the dominant ear than the non-dominant ear.
Key points
- Prospective single-blinded design with the audiologist blinded to dominant ear status.
- High-frequency audiometry (>8 kHz) was used to assess hearing outcomes.
- The study included 100 mobile phone users with a mean age of 27 years.
- A within-person comparison was used due to lack of a non-user control group.
- The dominant (phone-used) ear showed significantly more high-frequency hearing loss than the non-dominant ear (P < 0.05).
