BOA is a time consuming test as it is difficult to get a reliable & repeatable response from babies as young as 6 months for the same test stimulus.
BOA can take sometimes days & weeks to establish reliable hearings thresholds across various frequencies.
BOA cannot be ear specific test as we are presenting sound in a free field setup, hence always a better ear will response & in case of asymmetric hearing loss, we cannot establish each ear hearing levels.
Parents needs to understand that this test may need immense patience to establish reliable response from their babies & this may require several repeats
BOA is generally used to augment or add value to other objective tests. Therefore, this test should not be treated or interpreted as a standalone test to confirm diagnosis of hearing loss & also to fit amplification device.
