Move 鈥� Get into the habit of checking in with your ears, and if the sound is unsuitable, simply move somewhere else.
Block 鈥� If you can鈥檛 move and can鈥檛 change the noise, headphones can help. Consider using sounds like birdsong. I don鈥檛 recommend music, as it often replaces one distracting sound with another.
Seek silence 鈥� Silence is the baseline for all sound, so it鈥檚 a great way of recalibrating your listening and regaining your sensitivity to the adverse effects of noise. Give yourself a few minutes of silence every day.
