The polar bear makes a 'Growl' sound
The Pinna/Pinnae collects the sound waves.
The pinna (external ear) collects the sound and channels the sound into the ear canal.
The main difference between a supercardioid and cardioid microphone polar pattern is the directionality of sound they pick up. A supercardioid microphone is more focused and picks up sound from the front while rejecting more sound from the sides and rear compared to a cardioid microphone, which picks up sound mainly from the front but also captures some sound from the sides.
The main difference between a cardioid and hypercardioid microphone polar pattern is the directionality of sound they pick up. A cardioid microphone is more sensitive to sound from the front and less sensitive to sound from the sides and rear, while a hypercardioid microphone is even more focused on sound from the front and has a narrower pickup angle, making it better at rejecting off-axis noise.

The pinna of the ear collects sound waves. This is the part you see on the side of the head.
The outer ear collects and funnels sound waves to the eardrum, where vibrations are carried into the middle ear.
58 degrees because it is closer to 69 degrees.
Sound waves are 'collected' by the ear drum. This is a film stretched across the ear canal. Much like it's namesake, it responds to sound waves by vibrating. These vibrations are read as electrical signals by your nerves, and it is transmitted to brain as impulses.
Cardioid microphones pick up sound mainly from the front, supercardioid microphones have a narrower pickup pattern with some sensitivity at the rear, and hypercardioid microphones have an even narrower pickup pattern with more rejection of sound from the sides and rear.
You hear animal sounds like polar bears, wolves, and foxes.
