This is the second whistle I made, this one it has a very loud sound and two different tones. The sound of this whistle is over 120db, the pain threshold (https://ec.europa.eu/health/opinions/en/hearing-loss-personal-music-player-mp3/figtableboxes/table-1.htm) so ONLY BLOW WITH ALL YOUR MIGHT IN CASE OF EMERGENCY.
The https://recursostic.net/medidor-de-ruido-online/ measures aren't as much precise as other instruments and applications. However, I have compared more websites and apps.
