Where can I find a smoke detector for the hearing impaired, where the

not here high frequencies, which is common among the elderly.

Hello Mschwab and thanks for your question.

Loudenlow, inspired by a popular “Dear Abby” letter calling for better
smoke alarms for seniors, designed this product for people with high
frequency or high pitch hearing loss. It provides a loud, low pitch
audible alarm which is easier for many people to hear.
Read the Dear Abby letter here:

I tried Loudenlow and even ordered one from them.  2 months later they
emailed my money back, saying they had production problems.  Any other
sources you may be aware of?

Thanks for the response.  Matt is correct.  I reordered and received a
smoke detector from Loudenlow several months after the above post, and
my mother can hear it clear as a bell.  It's a great product, and
fills a needed niche given the great # of elderly with this type of
hearing loss.  The company was a pleasure to deal with both during the
production problems, and again later when this was available.  I
highly recommend this product!

SafeHome ( has just released a Smoke detector package
that Alerts your neighbors (multiple neighbors if you want). This
would be ideal for the hearing impaired where no amount of audio or
flashing lights would wake them.
