Unfortunately, deducing that your toddler has hearing loss is often easier said than done, as hearing loss may be gradual. Therefore, if you clap directly behind them, they will probably still react if the hearing loss is gradual.
Instead, here are some signs your toddler may be losing their hearing.
Little to No Speech Effort
By 12 months, your toddler should be able to babble or make sounds like "Mama." If your toddler is older and can already respond to simple sentences, you may notice that they respond to sentences inappropriately, demonstrating that they misheard the sentence.
Poor Attention
Most toddlers have very short attention spans. In fact, studies show that toddlers aged 16-19 months generally have an attention span of 2-3 minutes and 3-6 minutes by 20-24 months of age. By 36 months of age, they can maintain attention for 5-8 minutes.
However, if you notice that they don't meet these attention benchmarks when engaging with sound-related activities (toys with noise or speech) or become frustrated with background noise, it may be a sign they have hearing loss.
Fails to Follow Sound Source
By six months of age, a toddler should be able to turn in the direction of a sound. However, if they are unable to identify the source of a sound correctly, it might be a sign of hearing loss.
