It’s normal for adolescents to not “hear” you when you’re requesting they perform onerous tasks- but if you notice this more often, your adolescent may actually not be able to hear you. Adolescent hearing loss is on the rise; currently, about 1 in 5 adolescents has measurable hearing loss, as opposed to 1 in 20 in the 1990s.
We usually attribute adolescent hearing loss to loud music, so why a change now? Ridiculously loud concerts have been around since at least the late 60s. When the Walkman was introduced in the 1980s, teens with headphones played their favorite tapes so loud that everyone in the house could sing along. In the 90s, I turned my father’s stereo up to the max when playing Alice in Chains, and enjoyed feeling the floor vibrate.
