Hey DumbNerd,
Just FYI about some terminology, if you are in Grade 10 doing Unit 1&2 content now, your research investigation is called FA3 (rather than IA3) as this stands for "Formative Assessment 3". Assessments starting with "I" only refer to the ones in Grade 12 (Units 3&4) which count towards your ATAR. No stress tho 😀.
As for your research investigation, I need to also know your claim to give a more accurate answer. I just want to quickly note that ensure you keep your 1st dot point within the confines of your RQ. Your RQ determines the scope of your investigation and you have specifically stated "the hearing health of Australian teenagers" so when you discuss the first point, don't talk about other age groups but rather investigate how listening to music now affects their hearing when they are older, if that makes sense.
Considering this is a physics assignment, I can only assume that your claim and RQ focuses on sound waves (i.e. sound waves, frequency, wavelength, longitudinal waves etc.). So, I would highly recommend for you to discuss how earphones create sound waves and thus, what makes them harmful to the human ear. From your RQ, the bottom line is that you have to investigate how sound is good/bad for health. So, discuss how different frequencies (i.e. pitch of sound), different amplitudes (i.e. volume of sound) and different durations (i.e. time) affect the human ear (feel free to discuss how the tympanic membrane vibrates and transforms the vibrations to mechanical movements of the stapes, malleus and incus etc.). I would maybe alter your RQ very slightly and add "pitch" into the brackets as well so you can discuss the frequency of sound waves and make it more physics-y.
The first point of contact should be your teacher so please ask them but my strong opinion on this would be that adding the "sound wave stuff" is very important to the RQ - its how you show off your physics knowledge.
Anyways, hope that helped and feel free to be confused about what I said and ask questions 😆.
