Sound is louder when a vibrating source is held to a sounding board because more surface is forced to vibrate, pushing more air. true or false?

True

Explanation:

A sounding board has the property of receiving a sound wave and transforming it into vibration of the air molecules inside it; resulting in amplification or modulation of sound.

In other words, when the sound waves pass through a sounding board, the resulting sound is louder (amplified) because its surface is forced to vibrate by the air molecules present within the mentioned sounding board.

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.

think its the third option
