To answer the question above, you will describe a device that can enhance (or improve) your hearing ability in the wild. To do this, think like an engineer! To describe the criteria of your design, ask yourself, what does my hearing enhancer need to do? To describe the contraints of your design, ask yourself, what are the limits to my design?
Example of criteria- My hearing enhacer needs to be comfortable to wear, come in defferent sizes, lightweight ... etc.
Example of constraints- To build my hearing enhancer, I can only use the materials my teacher gives me, must cost below $10 to make... etc.
There are no right or wrong answers. Be creative!
