Re: Multifrequency Tympanometry
Hello Navid and List,
A technical comment:
The resonance frequency is proportional to the square root
of the stiffness, and indirectly proportional to the square root
of the mass.
A sphere of mass M on a spring of stiffness (i.e., spring
In the SI (système international), the dimension
of M is kg, and that of the spring constant S is N/m
(Newtons per metre).
Tne Newton is the unit of force, i.e., of mass times
acceleration, and thus is equal to one kg * m / s^2.
So the dimension of the stiffness S is kg / s^2, and that of
the square root of (S/M) is 1/s, equal to the dimension of
