The Duolingo brass band
My country home where I was happily following the Arabic course has suddenly been invaded by twelve more family members. Suddenly, I am self-conscious with the "ta-daa" and occasional "ta-da-daaa!", which is a good 30 dB more that the teacher's voice and the right-or-wrong bell sound. For the moment, I have gone to settings and turned off the notification sounds, but I hope there will be more options from Duolingo in the future.
