This is why authorities insist on specific tones. If you use a random buzzer for an earthquake drill, people ignore it. If you play the standardized , people instinctively dive under tables.
The Japanese Earthquake Early Warning (EEW) sound is iconic. It is a rapid, high-pitched "ding-dong-ding-dong" chime followed by a synthetic voice announcement. For sound designers, this specific audio sample is the gold standard for realism. Its effectiveness lies in its contrast: the chime is polite yet urgent, cutting through the noise without inducing the sheer panic of a war-time siren.
: Record or find sounds with "crunchy" or "brittle" textures, such as crunched-up plastic folders, pebbles shifting, or sand. Granular Synthesis : Drag your recording into a granular synthesizer like Steinberg Padshop 2 Go to product viewer dialog for this item. or Phase Plant Processing :
Sensors detect fast-moving but less destructive P-waves (primary waves).
While not "alarms" in the technical sense, small shallow quakes can produce audible rumbling or booming sounds caused by high-frequency vibrations hitting the surface. USGS (.gov)https://www.usgs.gov Earthquake Booms, Seneca Guns, and Other Sounds - USGS.gov

The primary goal of any emergency alert is to cut through "ambient noise." In a bustling city, a quiet home with the TV on, or a noisy factory floor, a standard doorbell or siren might be lost in the background. The earthquake alarm sound effect is designed to sit in specific frequency ranges—usually between 500 Hz and 5000 Hz. This is the "sweet spot" where human hearing is most sensitive.
“BEEP-BEEP-BEEP-BEEP — (pause 1 sec) — BEEP-BEEP-BEEP-BEEP”
Why is a specific more effective than a generic buzzer? The answer lies in Pavlovian conditioning and frequency-specific arousal.
