I have been investigating automatic recognition of alarm sounds, which form a distinctive and important set of sounds. Here are some the examples I have collected:
| Car/truck horns | horn 1 | horn 2 | horn 3 | horn 4 | horn 5 | horn 6 |
| Electronic telephone rings | phone 1 | phone 2 | phone 3 | phone 4 | phone 5 | phone 6 |
| Palm pilot alarms | palm alarm 1 | palm alarm 2 | palm alarm 3 | palm alarm 4 | palm alarm 5 | palm alarm 6 |
| Sirens | siren 1 | siren 2 | siren 3 | siren 4 | siren 5 | siren 6 |
The 'palm alarms' I recorded myself. Most of the rest I got from searching for sound examples on the web. Some of the telephone rings were recorded by my former colleague Victor Stein.
