Yes, audio speakers can harm your hearing in time, if you use them too often and too loud. Any sound that goes beyond 75 decibels can produce damage to a human being’s tympanum. So be careful what you listen, and especially how you listen!
I could recommend you a less expensive solution for steam cleaners, which is called Spick & Span. You can find it in any supermarket. The idea is that you should mix this solution with a little bit of fabric softener in order to cut down on sudsing.
Of course there are baby monitors for deaf parents! They have to keep an eye on their babies as well! The difference is that these baby monitors work on light signals and vibrations. The latest generation of baby monitors are equipped with a type of wireless feature.
As in the case of the handheld vacuum cleaners, handheld steam cleaners as not as performant as regular steam cleaners so you cannot expect them to clean absolutely everything. Unfortunately, from my own experience, this type of cleaners are really made for small stains that don’t need other chemicals added on them in order to clean. I own a handheld steam cleaner and I use it when I’m traveling.
It depends on the personality and behavior of the babies. Baby monitors can be removed even after a week since having been brought home, others are not removed even after 1 year and a half! My house is tiny and I immediately realized that I could hear my baby scream even if I were in the garage, so I got rid of it after a week.
You would probably find this weird, but my mother rents carpet cleaning equipment like that from the grocery store. They have a carpet cleaning machine they always keep at the entrance and they offer it for rent regularly. But I’m sure you can rent one from a cleaning company.
Well, air fresheners can puff as often as you set them to spread their odor. Common types of air fresheners can puff from 9 to 9 minutes, or once in 18, 27 or 36 minutes. I always set mine to puff once in 36 minutes, but I am not a smoker. Smokers make them puff more often.
If the frozen food is your problem, you should try, instead of having two refrigerators, to have one refrigerator and one large freezer. My mother has the same problem with freezing compartiments space and a freezer did it for her.
