What are the two main functions of voice?
Filer function and Source function
What is Boyle's Law?
The pressure of a gas is inversely proportional to its volume (temperature remaining constant)
-If you increase this volume, then the pressure will proportionately go down. The greater the volume, the lower the pressure
What is Pressure?
-The foce exerted per unit area of resistance (pressure applied against a resistance) (think of LBs of air pressure in tires, the more air you put in them, the more the LBs of pressure increases
What is the Intensity of a Sound?
-How much pressure is generated by the sound wave as it travels through the air
What is Dalton's Law?
In a mixture of gasses, each gas molecule acts as if it alone occupied the container. Think of cell membranes and muscle cells on the other side with a lot of CO2, and the cell membrane has a lot of O2 so they will travel to the opposite side of least resistance
What is Hook's Law?
Uses the force of elasticity. The elastic force of an object is directly proportional to the amount of displacement (think of a bra hook, how it recoils after it is snapped)
The force an object exerts to restore itself when displaced from rest
The thorastic cavity is an airtight container. This air pressure is always ____ than atmospheric
The diaphragm is at the bottom of the thoracic cavity. It is a muscle of _______
Inhalation. Whenit contracts, it moves down
One way to make the thoracic cavity larger is to contract the diaphragm. What is another way?
-Contract the other muscles of inhalation. These raise the rib cage up and out
How are the lungs connected to the outside air?
-Via the trachea, pharynx, mouth, and nose.
When the thoracic cavity is made larger, the air pressure becomes more __.
How does air rush into the lungs?
As we begin to inhale, the pressure in our lungs is below atmospheric causing air to rush in
To exhale, what do we do?
contract the muscles of expiration (pulling ht rib cage down),you could also quit contracting the muscles of inspiration which allows the diaphragm to recoil back up.
Gravity (passive expiration), the muscles of expiration, and what else helps with expiration?
Relaxation pressure. The pressure of the lungs by the lung elasticity. This is hooks law but the process is called relaxation pressure. This refers tot he elasticity of the lungs. During inhalation, the lungs expand, so if you could independently use the lungs, you could use the elasticity of the lungs to expel the lair
Recoil of the abdominal viscera:
When the liver and other organs under the diaphragm helps the diaphragm return to resting position.
Loudness of a production correlates to what?
The muscles of inhalation keep contracting once the speaker has used all the air. Why is this?
By keeping this contracted, the lungs remain high in the chest and the elasticity of the lungs is used
What is Flow?
It is expressed by the term volume velocity. How fast a volume of air flows (speed of air as it flows)
What is Ohm's Law?
Pressure = Flow (resistance)
Flow = Pressure/Resistance
Resistance = pressure/flow
What is Tidal Volume
The volume of air breathed in and out without conscious effort. The volume of air inhaled and exhaled at rest.
Inspiratory Reserve Volume (IRV)
The additional volume of air that can be inhaled and max effort after normal inspiration
Expiratory Reserve Volume (ERV)
The additional volume of air that can be forcibly exhaled after normal exhalation
Vital Capacity (VC)
The total number of air that can be exhaled after a max inhalation VC = TV + IRV + ERC
Residual Volume (RV)
the volume of air remaining in the lungs after max exhalation (the lungs can never be completely emptied)
What is total lung capacity?
TLC = VC + RV
The volume of air breathed in 1 minute: TV(breaths/minute)
People who talk on ERV tense their larynx and are at risk for what?
Do we use much IR or RV when we talk?
Not really, we simply inhale faster and have more controlled exhalations
Subglottic pressure = what?
Pressure in your esophagus should increase when you are loud and exerting force, and decrease when?
When you inhale
What is the easiest way to measure pressure?
What is a Spirometer?
measures the volume of exhaled air.
Why do the external intercostal muscles (muscles of inhalation) continue to contract?
The continue to contract to keep the rib cage up and allowing the pressure to stay consistent and not go up as muc. There is enough lung elastic force to produce the subglottic pressure. This uses Hooks law.
At what point during exhalation do the internal intercostals initiate?
When the volume gets to the point when the elastic force is spent
What is End Inspiration?
It is the end of total volume inhale. When the volume of air in the lungs reaches that of end inspiration and the lung elasticity is no longer sufficient to supply the sublottic pressure.
