I haven't heard anything so funny in quite a long time.

"It was some of the best news we've heard in a long time."

This is the first I've heard of it in a very long time.

It was the sort of voice that she had not heard in a very long time.

It was a voice he hadn't heard in a long time.

He hadn't heard his own language in a long time.

We have not heard from him in a long time.

It was the first good news she had heard in a long time.

Even if you have not heard it in a long time?

One of the best songs I have heard in a long time.
