Higher Q indicates a lower rate of energy loss relative to the stored energy of the resonator; the oscillations die out more slowly. A pendulum suspended from a high-quality bearing, oscillating in air, has a high Q, while a pendulum immersed in oil has a low one. Resonators with high quality factors have low damping so that they ring or vibrate longer.

In a damped Harmonic Oscillator, DHO, quality factor
Q = energy stored in the oscillator / energy lost during one oscillation or
= energy stored / energy lost in one radian of oscillation
Q = ω / (b/m)
The frequencies are not reduced. The amplitude of oscillation are reduced. The energy stored is reduced each cycle.
