Detecting bone conduction in your skull can be an interesting experiment. Bone conduction is the transmission of sound vibrations through bones, and it allows you to hear sounds even if your outer ears are blocked. Here's a simple experiment you can try to detect bone conduction:
Get a tuning fork: You'll need a tuning fork, which is a small metal device used to produce a specific musical note when struck.
Strike the tuning fork: Hold the tuning fork by the stem and gently tap it on a hard surface to make it vibrate.
Place the tuning fork on your head: Press the base (the part that vibrates) of the tuning fork against your skull, near your temple or behind your ear. Make sure the stem is pointing forward, perpendicular to your skull.
Listen for the sound: Pay close attention to the sound you hear. You should be able to hear the sound of the tuning fork, even though your outer ears are not involved.
Compare with regular hearing: After detecting the sound through bone conduction, hold the vibrating tuning fork near your outer ear (without touching it) and listen to the sound again. You should notice a difference in the quality and loudness of the sound between bone conduction and air conduction (the normal way we hear through our outer ears).
Remember that bone conduction is not a substitute for regular hearing and is primarily used in specialized hearing devices. If you have any concerns about your hearing or suspect any hearing issues, it's essential to consult with a healthcare professional or an audiologist who can perform proper hearing tests and provide appropriate advice and guidance.
