Simulating sunlight is relatively easy; look for lamps characterized as "full spectrum". Point them down from high places rather than up from low. Noise reduction is hard. The fastest, most efficient solution is to wear a pair of reusable, washable earplugs. If you buy them with a brightly colored cord connecting them, people will usually notice when they approach you. Next best is external ear defenders, the kind used for shooting sports. People will definitely notice that. The downside to both methods is that most people do not like having things inside or on their ears for hours at a time.
