Hearing and hearing problems
Maelekezo
In this topic you will learn about hearing and hearing problems in children.
How we hear
- Our ears collect sounds
- The sounds travel through the three parts of the ear
- The sounds are changed into electrical signals which are sent to the brain
- When the signals reach the brain, we hear the sounds and can recognize them.
Ili kuweza kusikia vizuri, sehemu zote za sikio zinapaswa kufanya kazi vizuri.
How sound travels through the ear
Hearing problems
People with hearing problems have difficulty hearing or recognizing sounds.
Kazi
kwenye jozi:
- One person blocks their ear on both sides with their finger or by using earplugs
- The other person uses their normal voice and tries to have a conversation.
This is how it feels to have mild to moderate hearing loss.
Mild to severe hearing loss
Hearing loss is also known as ‘hard of hearing’.
A child with mild, moderate or severe hearing loss cannot hear as well as other children.
They have difficulties with:
- Hearing what other people are saying in quiet and noisy environments
- Kufanya kazi za kila siku, ikiwa ni pamoja na kujifunza, bila msaada wa Bidhaa Saidizi kama vile vifaa saidizi vya kusikia.

Majadiliano
Jadili na wanafunzi wenzako:
- Do you or does anyone you know wear hearing aids?
- Je, matokeo yatakuwaje kwa mtoto anayehitaji vifaa saidizi vya kusikia lakini hawezi kuvipata?
Je, kusikia kunapimwaje?
Kusikia kunapimwa kwa kutumia kipimo cha kusikia.
This involves the child listening to sounds through headphones and indicating which ones they can hear.
Sauti hutolewa na kipima sauti. Kwa mfano, kompyuta kibao ya kidijitali au simu janja iliyopakiwa na programu ya upimaji ya kusikia.
