Comparing how the sound travels from my EST Genesis Horn vs my Piano alarm sound and tablet alarm

In this video, I compare my EST Genesis fire alarm horn I have on the wall vs my piano, and tablet fire alarms to see how well they do. In the video, the EST Genesis and the piano fire alarm sound do a perfect job of attenuating or making the sound travel very well as the reason why is because the Genesis is a fire alarm that's supposed to meet UL and NFPA 72 safety codes to make sure the alert travels very far in a building to get people's attention at a very loud volume and cut through background noise easily with a high frequency broadband tone. The piano speakers travel the same way as a fire alarm as a coincidence because digital piano speakers are designed for music concerts so that way the spectators in the crowd can easily hear the performance wherever they are in the crowd which is useful as it prevents the player having to hear the piano very loud and hurt their ears while playing just so the audience can hear. However tablet and phone speakers don't do well carrying fire alarm sounds across long distance because they're basic speakers that can only play audio when you're using them in front of you and don't have any complex speaker grilles. 0:00 Intro 1:42 EST Genesis Horn vs EST Genesis Tablet Tone 3:47 EST Genesis Horn vs Piano Fire Alarm Tone
