hearing science quiz 2

As frequency increase,

Reactance due to mass increases, reactance due to stiffness decreases

The frequency of free vibration is also called resonant or natural frequency

True

Mass reactance is greater at high frequencies

True

Stiffness reactance is greater at lower frequencies

False

resonant frequency

Mass and stiffness reactance cancel each other, oppositions to vibration comes from resistance component

Air and water have the same impendence

False

Rate at which work is done

Power

True statement

Harder to get massive object to vibrate quickly, harder to get stuff objects to vibrate slowly

Bandpass filter has ___ cutoff frequencies

2

Vey small portion of energy is transmitted if the impendence mismatch is large

True

Filter which is used to elimate just one frequency is called

Notch filter

Type of filters have 2 cutoff frequencies

Bandpass and band stop

True statement for tube open both ends

Antinode form at both ends

Time period of a complex t periodic wave is equal to

The time period of the fundamental frequencies

In a open tube at one end

Only odd harmonics can be produced

Tube length and fundamental frequency are inversely proportional to each other

True

Three pure tone - 6 hz, 4 hz, 3hz, 1 m tied both ends,

Lowest natural resonant frequency is 6hz

Tube open at both ends can resonate at odd and even harmonics

True
