Does it land?
Six short comparisons of a synthesized spacecraft thruster. You hear two renders, A and B, in random order, and say how well each one lands: 1 means it does not, 5 means it does. Then give each a single word. Use headphones or speakers at a comfortable level, and a quiet room if you can.
Rate both sounds and give each exactly one word (no spaces) to continue. You can replay as often as you like.
