“Never put anything smaller than your elbow into your ear” is something we’ve been wisely cautioned against at some stage or another. But more of us are ignoring this advice.
We use in-the-ear-headphones to listen to music, car keys and hair pins to scratch that particularly unpleasant itch, and hearing aids to enable better communication.
Many of us also use disposable foam earplugs to protect from damaging noises in the workplace, or to block the noise of snoring partners, loud traffic outside bedroom windows, dogs barking and any other bothersome sounds that prevent a good night’s sleep.
