1.   Our ears, for example, can distinguish higher pitches from lower frequencies.

2.   The other patients were excluded for lower frequency of incontinence or absence of severe urgency.

3.   Between these two maxima there is a lower frequency of depths representing the more shallow regions of the oceans.

4.   And beyond that are even lower unseeable frequencies called radio waves.

5.   Acoustically speaking, African-American men are generally said to speak in lower frequencies and more flexible ranges, for a more deeply resonant sound.

6.   Despite the studies, said Heath, no form of EMF energy at frequencies lower than those of X-rays and ultraviolet radiation has been shown to cause cancer.

7.   Giuliani also said Tuesday that his administration was seeking to acquire a noncommercial station with a lower frequency to continue the programming of the FM station.

8.   Moreover, Readhead said that an analysis using only the high notes yielded the same cosmic parameters as a previous analysis based on the lower frequencies.

9.   The image that emerges is how a celestial object might look if the rods and cones in the human retina could be replaced with ones sensitive to lower frequencies.
