Cheapest way i can think of: buy a celling tile case and a tacker, cut the celing tile un a T shape and tack them on both side between each of the truss. No need to put anything between them. That’ll cost around 100$.

Forget the drywall celling for a while you should at least replace all the stuff that’s gonna be stuck in there for peace of mind. Then you can think about it.

You should get that celling tile for the whole celling asap this will help with the soundproofing of the first level. Consider extra soundproofing after this.

Ah yes worldnews.lm the place where dictators are the good guy

Background: On 30 August, President Volodymyr Zelenskyy reported that at a meeting of the National Security and Defence Council of Ukraine, it had been decided that a comprehensive inspection be conducted of the validity of decisions made by military medical commissions since 24 February 2022. These are decisions on disability and unfitness for service that were or may be related to corruption violations. All cases where the decisions were unreasonable and illegal should be investigated by law enforcement agencies, the president said. In addition, Zelenskyy announced that the system of determining fitness for military service must be reassessed to make it easier for commanders to recruit soldiers for combat missions and to prevent the concept of limited fitness from being manipulated.
