Incapacitating buzzing

tinnitusAfter a hard week’s work, near the end of the day at my office, a middle-aged man came in looking very tired. He seemed concerned, his eyes were very red and he swayed slightly from side to side. He looked like he hadn’t slept in a week. Mister Zé Alfredo sat down and said:

- Doctor, I can’t sleep anymore. There’s too much noise. A terrible buzzing sound. It never stops! It’s driving me crazy … (silence) … Can you destroy my hearing? I don’t want to hear anymore. To tell you the truth, the way things are now, I don’t want to go on living.

For me, a person who loves researching the auditory system and the details of its functioning, his words seemed incompatible with reality. How could hearing, the only sense capable of sending information from far away in a 360º circle, be so despised by this individual?

Buzzing in the ear affects more than 28 million Brazilians, most of whom are adults over the age of 40 (click here to see report). A host of infections, metabolic disorders, diabetes, hypertension, perforated ear drum, etc. are only some of the likely causes of buzzing. Despite the difficulty in accurately diagnosing its origin – some types are of unknown origin – all is not lost, because most cases are treatable.

 

Buzzing can be treated

Believe it or not, turning on the radio or the television (not too loud) may help people with mild cases to sleep, at least until they get specialized treatment from an ear, nose and throat (ENT) doctor. Treatment is wide ranging, from antibiotics and mineral replacement to auditory rest and changes in food habits, depending on the etiology. In the most severe cases and those of unknown origin, patients are referred to a speech therapist for adaptation therapy, after which they “no longer notice” the buzzing.

Perfect pitch

au_carnegie_hall            At Carnegie Hall in New York City, the local philharmonic orchestra has a full complement of musicians.  More than 100 musicians play together, allowing theater goers to experience a bit of heaven, at least musically speaking.

            For me, seated in the seat J45, in the middle of the theater, everything seemed perfect. But it wasn’t. Everything was not so perfect for the conductor. Suddenly he interrupted the performance by rapping his baton on the pedestal. He looked upset. Something was irritating his ears. Then he said:

- Second row of violins, fourth instrument, third string, out of tune, half semitone higher, please!!!

            The beauty of the spectacle from then on didn’t matter to me anymore. The unexpected occurrence that showed the conductor’s perfect pitch demonstrated to me how high human creativity can reach and how much most of us can still grow.

 

What is perfect pitch?

            The capacity of mentally visualizing sound frequencies, perfect pitch (click to see documentary) or of humming the same pitch (active perfect pitch), does not appear to be related to any significant structural modification, but rather to a tendency of central physiological mechanisms that can be stimulated, mainly up to five years of age.

            Studies show (see SACKS, 2007) that we can train our ears to obtain an even more prodigious musical journey, but the genetic factor apparently determines the greater likelihood of the emergence of this skill.
