Online timer for 57 seconds
While listening closely to a tsunami signal during a practice check, let a 57 seconds countdown run where you can glance at it without missing changes in the sound. It marks a short listening window while your attention stays on the signal, nearby instructions, and what is happening around you.
During the practice signal, the preset interval gives you a clear reference without making the countdown the main task. If the exercise leader sets a different listening window, the duration can be changed directly on the page to match it. A longer setting suits a signal that continues, while a shorter one can isolate a particular section.
If the practice requires another listening check straight away, restart the countdown only when the next signal or repeated section begins. Keeping that starting point consistent makes the two listening windows easier to compare. If instructions interrupt the exercise, wait for the repeat rather than letting an unattended countdown stand in for what you heard.
Common questions
What if the tsunami practice signal continues beyond this listening interval?
Keep listening to the signal and follow the instructions given during the exercise. The countdown marks only the selected observation window, so its duration can be extended when a longer comparison is needed.
What if the tsunami practice signal stops before this interval ends?
Note where the sound stopped and remain attentive to the exercise. If the signal is repeated, restart the same interval when the repeated sound begins.
