The word "study" is spelled /ˈstʌdi/, with the stress on the first syllable. It is a common verb used to describe the act of learning or exploring a subject in depth. "Disturb," on the other hand, is spelled /dɪˈstɜːrb/, with the stress on the second syllable. It is a verb used to describe the act of interrupting or disrupting something. When combined, "study at disturb" would not be a natural or commonly used phrase in English.
