Yes, lop ears affect a rabbit's ears compared to a radar-eared rabbit. Lop-eared rabbits are prone to deafness and hard of hearing due to the muffling of sound waves through their ears. Imagine covering your ears and hearing the world through them. Radar-eared rabbits can easily swivel their ears to capture the most sound without obstruction.
