I don't mind being seen as silly (again) 14 houses in view from my door. Four nearest clapped last week, fireworks in next street maybe, train hooted a mile away. This week, 9th April, three more households.
Its a tiny something else to look forward to in these hard times.
Freinds in Scarborough are in old folks bungalows and flats, not many clapped but they could hear others beyond their railway, thats a mile or more so they were loud. The point is it CAN be heard.
