Yes, turning up the television and frequently asking for repetition are two of the most common early indicators of glue ear in children. Because glue ear involves the accumulation of thick fluid behind the eardrum, it creates a physical barrier that prevents sound vibrations from reaching the inner ear efficiently. This results in conductive hearing loss, which children often describe as feeling like their head is underwater. To compensate for this muffled sound, children naturally seek higher volumes and clearer verbal cues to help them understand the information they are missing.

The Physics of Muffled Hearing
To understand why a child needs a higher volume, it is helpful to look at how fluid interferes with the mechanics of the ear.
In a healthy ear, the eardrum vibrates freely when sound waves hit it. These vibrations are then passed through three tiny bones to the inner ear. When the middle ear is filled with fluid, the eardrum becomes stiff and heavy. It can no longer vibrate effectively, which significantly reduces the volume and clarity of the sounds being transmitted. Most children with glue ear experience a hearing drop of about 20 to 30 decibels, which is roughly equivalent to wearing a pair of earplugs.
Turning Up the TV and Devices
Increasing the volume is a direct compensatory behaviour. By making the sound louder, the child is attempting to force enough vibration through the fluid filled space to reach the auditory nerve.
- Sitting Closer to the Screen: You may notice your child sitting unusually close to the television or holding a tablet right up to their face. This is often done to catch both the visual lip reading cues and the direct sound.
- Inconsistent Volume Needs: A child hearing can fluctuate depending on how thick the fluid is that day. They may need the TV at a normal volume one day but require it much louder the next if they have developed a fresh cold or nasal congestion.
- Missing Quiet Details: They might follow the main action of a show but miss the dialogue or subtle sound effects, leading them to ask questions about what is happening despite the high volume.
The Need for Repetition and Clarification
Asking what or saying pardon frequently is a sign that the child is receiving an incomplete auditory signal.
- The Cocktail Party Effect: Children with glue ear struggle immensely with background noise. In a quiet room, they might hear you fine, but if the washing machine is on or other children are talking, they cannot filter your voice. This leads to constant requests for repetition.
- Mishearing Similar Words: Because high frequency sounds like s, f, and th are often the first to be muffled, a child might confuse words that sound similar, leading to confusion and the need for clarification.
- Looking for Visual Cues: You might notice your child watching your mouth intently while you speak. They are subconsciously using lip reading to fill in the gaps left by their muffled hearing.
Is it Selective Hearing?
Many parents initially mistake these signs for selective hearing or disobedience. It is important to distinguish between a child who is choosing not to listen and one who physically cannot hear.
If a child responds when you are face to face in a quiet room but ignores you when your back is turned or when you call from another room, this is a strong indicator of a physical hearing barrier rather than a behavioural issue. Selective hearing is usually consistent regardless of the environment, whereas hearing loss from glue ear is significantly worsened by distance and ambient noise.
To Summarise
Turning up the TV and asking for repetition are primary coping mechanisms for the conductive hearing loss caused by glue ear. These behaviours are not signs of naughtiness but are evidence of a child struggling to stay connected to their auditory world. Recognising these subtle signs early can lead to a quicker diagnosis and prevent the frustration and exhaustion that children often feel when they cannot hear clearly.
If your child has started increasing the volume on their devices or frequently misses instructions in noisy environments, the next clinical step is to arrange a tympanometry test to confirm if fluid is present behind the eardrum.
Will my child hearing return to normal if they stop turning up the TV?
Turning the TV down will not fix the hearing; the hearing only returns to normal once the fluid in the middle ear drains or is absorbed.
Does glue ear affect one ear or both?
It can affect both, but if it only affects one, the child might turn their head to one side to hear the TV better with their good ear.
Can turning up the volume damage their hearing further?
While very loud noise can be harmful, the volume levels used to compensate for glue ear are usually not high enough to cause permanent damage, especially since the fluid itself acts as a protective dampener.
Why does my child hear me fine sometimes but not others?
This is the hallmark of fluctuating hearing in glue ear. Changes in position, atmospheric pressure, or nasal congestion can all change the thickness and position of the fluid, altering hearing levels throughout the day.
Should I use headphones to help them hear better?
Headphones can help by delivering sound directly, but they can also make it harder for the child to hear what is happening around them in the room. It is better to address the underlying fluid.
Is asking for repetition a sign of a processing disorder?
While it can be, if it is accompanied by turning up the TV and occurs after a cold, glue ear is a much more likely physical cause that should be ruled out first.
