noisome, noisy

The human ear can detect only one of these words, that is, noisy. The other, noisome, is better associated with the nose. Noisy means “loud.” Noisome means “offensive,” “disgusting,” or “dangerous” as in noisome fumes.

Example: We had a hard time deciding which bothered us more, the noisy party next door last night or the noisome odor left over the next morning.
