Why Does My Voice Sound Different on Recording and Treatment Options

Every so often, I have a patient who presents to my office with a complaint that their voice sounds different on recording than what they themselves hear.

In particular, singers who come in state specifically that their vocal recordings sounds slightly flat when they thought they were singing in perfect pitch.

So why does this happen? Unfortunately, it is physics and fundamentally integrated to how the ear, skull, and sound transmission work. In other words, it can't be "treated" with surgery or medications.

What other people hear when you sing or talk is air conducted sound that gets transmitted through the ear canal, eardrum, middle ear bones, and ultimately to the cochlea hearing organ (pathway A). Image modified from Wikipedia.

The sound the individual singer/talker hears is not only sound transmitted via the air (pathway A) but also by vibration of the skull itself directly to the cochlea hearing organ bypassing the outer and middle ear completely (pathway B). The mechanical properties of the skull enhance the deeper, lower-frequency vibrations.

Therefore, when a talker/singer listens to a recording of their voice speaking/singing, the bone-conducted pathway that they consider part of their “normal” voice is eliminated, and they hear only the air-conducted component in unfamiliar isolation (what everybody else actually hears).

SO... what is a singer/talker to do if they are disturbed by the way they sound to others? Particularly, what is a singer to do when they always sing a little flat when they truly think they are singing in pitch?

One can wear earplugs in order to hear only bone-conducted vibrations and get used to their alter-voice and undergo speech/voice therapy. OR... accept that their voice IS different.

For singers, I highly recommend using HearFones Headsetwhich is a funny looking head device that allows an individual singer to hear what they really sound like and more importantly what the audience would hear! In addition, while using HearFones, the singer would be able to hear himself more predominantly over the rest of the ensemble thus helping him to improve the quality of his/her individual vocal quality output.

Over time, singers will be able to automatically adjust their singing such that they no longer will need such a device to sing in tune with others when in familiar surroundings. BUT... in new environments (new concert hall, outdoor arena, etc), it is not unusual that their singing may become off again...

This is why professional singers often wear earpieces that convey sounds recorded by microphones placed in the audience... and also why they sometimes sound flat and out-of-tune when they don't!

It's also why it is VERY important to rehearse in a new place before a concert.

Why Does the Nose Whistle in Some People?

Though most people like the professional nose whistler shown here require an instrument to enable the nose to whistle, in others it occurs naturally due to unique anatomic features within the nose.

Why might someone's nose whistle?

Septal Perforation

The most common reason it may occur constantly is due to a hole in the septum (septal perforation). The septum is a wall that divides the right nasal cavity from the left side. Normally, it should be straight and without any openings.

However, when a hole is present in the septum and it is in just the right size and place, whenever air is breathed in and out the nose, it will whistle. In this situation, the hole is the "window" of the whistle and the nose itself is the mouthpiece.

Correction of this problem is by either closing the hole (septal button or surgery) or making it bigger such that the aerodynamics eliminate the conditions conducive to nasal whistling. As an FYI, surgical correction of a septal perforation is quite difficult.

Septal Deviation and Some Nasal Congestion

The other situation when the nose may whistle, but only intermittently, is when there is a deviated septum. In this scenario, the septum rather than being straight, it is slightly crooked to one side making one side more narrow than the other.

Add some slight swelling of the nasal lining such that the opening of the nose is restricted to just right size and shape, and it may whistle.

This type of nasal whistling is akin to grass whistling (blowing between two thumbs holding a blade of grass).

Thankfully, the nasal conditions that lead to nasal whistling is quite rare and requires the perfect storm of just the right amount of septal deviation with just the right amount of nasal congestion.

As such, correction of this problem is fairly easy as one needs to change either the congestion causing the nasal lining to swell with a nasal spray or anti-histamine OR fix the deviated septum. If the inferior turbinates are enlarged, they can be reduced in size as well.

Of course, one can take this unusual condition and make it a positive feature worthy of a concert hall... WITHOUT the assistance of any instrument!
