Video gamers worldwide may be risking irreversible hearing loss and/or tinnitus

Video gamers worldwide may be risking irreversible hearing loss and/or tinnitus—persistent ringing/buzzing in the ears—finds a systematic review of the available evidence, published in the open access journal BMJ Public Health.

And given the popularity of these games, greater public health efforts are needed to raise awareness of the potential risks, they urge.

While headphones, earbuds, and music venues have been recognised as sources of potentially unsafe sound levels, relatively little attention has been paid to the effects of video games, including e-sports, on hearing loss, say the researchers.

Gamers often play at high-intensity sound levels and for several hours at a time, they add. And one estimate indicates that there were more than 3 billion gamers worldwide in 2022.

Reported sound levels ranged from 43.2 decibels (dB) (mobile devices) up to 80-89 dB (gaming centres) while length of noise exposure varied by mode and frequency of access–from daily to once a month, for at least an hour at a time, averaging 3 hours/week.

Impulse sounds consist of bursts lasting less than 1 second, with peak levels at least 15 dB higher than the background sound. One study reported that impulse sounds reached levels as high as 119 dB during game play; permissible exposure limits are around 100 dB for children and 130–140 dB for adults.

One study measured sound levels of 5 video games through headphones attached to the gaming console, and found that these averaged 88.5, 87.6, 85.6 and 91.2 dB for 4 separate shooter games, and 85.6 dB for a racing game.

“The findings suggest that there may be a need to prioritise interventions, such as initiatives focused on education and awareness of the potential risks of gaming, that can help promote safe listening among gamers,” they suggest.
