False alarms are certainly a pain. Not near as much, though, as when the alarm fails to get your attention when the smoke is real.

My dad plans to get one made by kidde an worry-free one

Kidde seems to be a very good brand.

I just wanted one that doesn't scare me as much
and one that reduced the false alarm

While installing your new smoke alarm it must be install on or near the ceiling with care taken to avoid dead air spaces.

Hope it will be useful for you.

We now have an new smoke alarm in our house and I have heard it before and it does not scare me as much as our old one which we had for 22 years

This is what our old smoke alarm looked like
