Why is the alarm in an analog mechanical clock louder than
a digital clock?

Because a small piezoelectric transducer is cheaper than two brass
bells and a solenoid. The same is true for the ringers in POTS
telephones versus modern electronic phones. Even those phones that
have a built in loudspeaker (for speakerphone) aren\'t very loud.

You can buy modern alarm clocks that will wake the deaf (and possibly
the dead). I have several friend and customers who need hearing aids.
Their houses are full or extra loud doorbells, phones, alarm clocks,
smoke alarms, CO alarms, motion detectors, burglar alarms, appliances
etc. As a concession to the neighbors, they usually wear cordless
headphones while watching TV or listening to the hi-fi. I setup an
IFTTT recipe to flash some of their house lights when some trigger
wants attention, but nobody seems to like or use it much.

This alarm clock includes a bed shaking vibrator:

More loud alarm clocks:

Note that \"extra loud\" is much like chicken eggs, which are sold in
supermarkets as large, extra-large and jumbo, where the sizes are
relative. Todays extra loud alarm clock is likely to have the same
alarm sound level as the older mechanical bell ringers.

I have an old Westclox USA-made wind-up I keep around in case there\'s a
long power-outage. Hasn\'t been one in recent memory that needed it, though..

looks just like this one, IDK when it was made maybe late 70s or 80s?

I just wound it to make sure it still runs and rings, seems OK. I\'ll
check back tomorrow to see how accurate it is!

Ah, the alarm sounds just like the first one from Pink Floyd\'s \"Time\":

Am testing some Chinse piezo beeper on my home RF motion sensor alarm system
Maybe you could solder one (3V) to your alrm clock ;-)
Very hard not to notice that beep!

Adding a tiny plastic horn to a piezo can make it massively louder, see any smoke alarm, but no-one wants to spend the extra 5p these days.

As a young teenager I had to get up early for some scout camping trip,
and I was worried I wouldn\'t hear my alarm clock. I had a sound activated
relay kit from Radio Shack, built on the perforated Red Plastic boxes. I
connected
a radio to the sound activated relay and an 8\" horn speaker to a the
Radio output.
I turned the volume high and in the morning, my alarm clock sounded,
triggered the relay,
turning on the radio, and I woke up for the camping trip.!
  Won\'t most digital clock radios, turn on the radio as the alarm, put
it on a Rap station,
and crank the audio level.
