Data is being shared with the WHO's Make Listening Safe initiative. Preliminary results released in March 2021, one year into the study, indicated that 25% of participants experienced ringing in their ears a few times a week or more, 20% of participants have hearing loss, and 10% have characteristics that are typical in cases of noise-induced hearing loss.[41] Nearly 50% of participants reported that they had not had their hearing tested in at least 10 years.
