Condenser microphones are the most common types of microphones you'll find in studios. They have a much greater frequency response and transient response - which is the ability to reproduce the speed of an instrument or voice.
protein-bound iodine test n. A test to determine thyroid function in which serum protein-bound iodine is measured. The American HeritageÂ® Stedman's Medical Dictionary
Iodine status is typically assessed using urinary iodine measurements. Urinary iodine reflects dietary iodine intake directly because people excrete more than 90% of dietary iodine in the urine [4]. Spot urine iodine measurements are a useful indicator of iodine status within populations [19,20].
