Here are the mistakes in the sentences:

1. The street is **more noisier** than that one.
- **Mistake**: "more noisier" is incorrect because "noisier" is already the comparative form of "noisy." It should just be "noisier."
- **Correct Sentence**: The street is **noisier** than that one.

2. Tom **usually take** the bus to school.
- **Mistake**: "take" should be "takes" because the subject "Tom" is singular.
- **Correct Sentence**: Tom **usually takes** the bus to school.

So, the corrected sentences would be:

1. The street is **noisier** than that one.
2. Tom **usually takes** the bus to school.
