Hearing Aid: inside components and types walkthrough

Section role: supports the 'Inside a Hearing Aid' section while the teacher formalizes the parts of a hearing aid and explains how they mimic the students' 'Sound Catchers' but with electronic power. Slides: (1) Title — 'Inside a Hearing Aid: How They Help Us Hear'; (2) Remember Your Sound Catchers — bullets: review the paper cones, how they collected sound waves; (3) What is a Hearing Aid? — bullets: tiny, powerful sound catcher, definition of hearing aid, simple diagram of a hearing aid; (4) Part 1: The Microphone — bullets: collects sound from the air, like our ear, visual of a microphone; (5) Part 2: The Amplifier — bullets: makes sound louder, uses battery power, visual of an amplifier symbol; (6) Part 3: The Speaker — bullets: sends loud sound into the ear, helps the brain hear clearly, visual of a speaker; (7) How Sound Moves Through a Hearing Aid — bullets: sound enters microphone, gets louder in amplifier, leaves through speaker; (8) Types of Hearing Aids: Behind-the-Ear (BTE) — bullets: sits behind the ear, good for powerful sound, visual of a BTE hearing aid; (9) Types of Hearing Aids: In-the-Ear (ITE) — bullets: sits inside the ear, more discreet, visual of an ITE hearing aid; (10) Choosing a Hearing Aid — bullets: why someone might prefer BTE (power), why someone might prefer ITE (looks), connects to the earlier 'Sound Catchers' by showing how electronic parts replace manual collection. Closing slide: 'Why might a person prefer one type of hearing aid over another?' — sets up a brief discussion.
