Hearing loss in children isn't always obvious. A child might pass a school screening, react when you call their name from across the room, and still be missing the softer sounds that carry meaning: the consonants in conversation, the teacher across the classroom, the friend across the lunch table. Knowing when to get a real evaluation is one of the most common questions parents bring to us. Here's how we think about it.
Why early matters
The auditory parts of a child's brain develop most rapidly in the first three years of life. They're shaped by the sounds the child hears, and what they don't hear, they don't learn to process. A child with mild, untreated hearing loss at age two doesn't just miss those two years of input; they lose ground that's much harder to make up later.
Even small interventions, started early, change the trajectory dramatically. That's why we don't wait when a parent's gut says something is off.
What to watch for, by age
Different ages, different signs. Here's what we tell parents at each stage.
Newborn through 12 months
Most U.S. states screen newborns before discharge from the hospital, but those screens catch the most severe losses. After that, watch for:
- No startle to a loud, sudden sound (door slam, car horn)
- No turn toward your voice when you call from out of view by 4 to 6 months
- Babbling that doesn't progress: still vowel-only at 9 to 10 months, no consonants emerging
- Quiet babies who "are just calm": sometimes they aren't hearing what would make them babble
1 to 3 years
This is when hearing-loss signs become more visible because language is taking off (or not). Watch for:
- Speaking much later than peers
- Saying words but with consistently distorted consonants (s, sh, t, k all fuzzy)
- Watching faces intensely, lipreading without realizing
- Frequent ear infections, a major contributor to fluctuating hearing
- Turning the TV up unusually loud
3 to 5 years
The classic preschool warning signs:
- "What?" being a primary word
- Tunes-out behaviour in noisy environments: restaurants, parties, classrooms
- Letter sounds your child can't seem to pronounce despite practice
- Withdrawing in group settings (kids with hearing loss often look "shy" first)
School-age
Often caught here through school screenings, but those screenings can miss high-frequency loss and unilateral (one-sided) loss. Watch for falling behind in reading or spelling without other obvious explanation, behaviour issues in noisy classrooms, "auditory processing" complaints from teachers, or simply asking for repetition more often than peers.
What an evaluation actually looks like
Pediatric hearing evaluations are gentle, age-appropriate, and explained as we go. For very young children we use behavioural observation and visual reinforcement audiometry: sounds paired with cute light-up toys. For older kids it's much like an adult evaluation but shorter and less clinical.
You'll be in the room. You'll hear the same sounds your child is hearing. We explain the audiogram before we leave the appointment.
Most evaluations end with "they're fine, see us in two years." That's a perfectly good outcome, and far better than guessing.
When in doubt
The single best piece of advice we give parents:trust your gut, and get it checked.A pediatric hearing evaluation is the same time and cost as a routine dentist visit. The downside of doing one when nothing's wrong is small. The downside of waiting two years to do one when somethingiswrong is enormous.
If you've been thinking about it for more than a few weeks, that's the answer.
