Narrative:

During climb out noise in the cockpit became so distracting it interfered with the safe operation of aircraft. Both pilots were forced to question each other and ATC controllers on communications in the cockpit. After landing I discussed the problem with contract maintenance. I advised of situation once again. The company continually refuses to address the primary problem; the overall noise level in the cockpit with the right recirculating fan off! There is no published limit. 60 db is acceptable as is 90 db. The company loves to focus on the secondary problem; which is the recirculating fan. As long as the db level is within 3 db's per a recent service tip the aircraft is good to go. Therefore; an aircraft with an overall db level of 73 is just as legal for flight as one with a 103 db level. This condition; along with the company's disregard for safety of flight issues; is dangerous and unacceptable. Left unchecked; this will lead to an accident.
