Hi,

Could you check this paragraph please?

"This research was carried out in the assembly and warehouse units of a car manufacturing company. The two experimental groups were selected from the assembly unit and the one control group from the warehouse unit (the individuals of this group were exposed to 70-80 dBA noise levels). The sample size in each group was 26 subjects, which were randomly selected, and the total number of participants in the study was 78 individuals."

Thanks!
