Best white noise machine?

Ash • Married 💍

Please help a tired momma out ladies! I cant put the girl down for naps in the day as she is woken up by noises outside (the building opposite us have construction work being carried out). And at night hubby and i have to creep around the house as to not wake her as shes such a light sleeper! Even floorboards wake her up! Takes her forever to go back down again!
