His friends have not heard from him in more than a year.

The voice on the other end was one she had not heard in 25 years, since high school.

They hadn't heard from him in more than a week.

He used a couple of words I hadn't heard in years.

I haven't heard of her in a century or more.

And not a sound was to be heard in the house.

I think great things will be heard from him in time to come.

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

He had never heard better news in all his life.

Then again, I also haven't heard anything from him in a while.
