Chest as a resonator - article incorrect.

I wish I had a source at hand, but the information in the article concerning the chest not having an effect as a resonator is false, and the source that says that is incorrect. Although the air only exits past the vocal folds, the sound travels bidirectionally. Bronchial resonance can result in pressure wave phasing at the point of the vocal folds, affecting their timbre.

If you want to hear this for yourself, record yourself saying something with full lungs and then again with nearly empty lungs. Try not to strain because that will affect muscular function, and therefore vocal timbre, more profoundly than chest resonance.

I personally have the academic & professional credentials to speak with some authority on this issue, and I know that's not good enough to change the article (thankfully!), so I'll try to find a source. Dcs002 (talk) 23:52, 21 February 2011 (UTC)[reply]

Ok, so I see my point is addressed in the Tracheal Tree section, but that leaves the "chest" as a rather ambiguous entity. If the chest refers to the thorax (as is the common usage here in the US, often meaning the anterior thorax), then it includes the tracheal (or bronchial) tree. If it refers to alveolar lung tissue or all the the non-airspace tissue within the thorax, it should say so.

Also, the tracheal tree is not only a factor at its own resonant frequency, but also at the harmonics of its fundamental resonance. Dcs002 (talk) 00:10, 22 February 2011 (UTC)[reply]
