This result is comparable to that of Brudzynski and Pniak (2002), in which 50
kHz calls were produced in anticipation of a social contact, although peak frequency of call during 'contact' behavior was lower than that of call during other behaviors in this study.
The maximal temperatures of the brass flange at the moment when the solder attains the liquidus temperature are from 820[degrees]C for the frequency of 25
kHz to 837[degrees]C for the frequency of 45
kHz.
The differences in thresholds predeployment and during deployment at the individual frequencies of 500 Hz, 1
kHz, 2
kHz, 4
kHz, and 6
kHz were then compared between groups with a one-way analysis of variance (ANOVA) using Statistical Package for Social Sciences (SPSS), Version 11.0 (SPSS Inc, Chicago, Illinois).
Figure 5 shows the power spectra for the pipe without a leak (screw without hole inserted into the bore-hole of the pipe) indicating frequency contributions between about 30
kHz (limit of high-pass filter) and about 150
kHz for both types of sensor, essentially independent of the pressure of the air (varied between about 400 and 800 kPa).
In the 96-kHz mode, the rolloff moves from 42
kHz to 28
kHz.
Shad in a lab tank will turn and swim away from a device emitting low-volume frequencies between 70
kHz and 110
kHz, which are characteristic of foraging dolphins, says Popper.
Values to be counted in
KHZ analysis are in terms of the amounts that parties would be willing to pay to acquire a right or possession, and amounts that parties would be willing to accept in exchange for a right or possession.
Most military aircraft, for example, have communication systems that are band-limited in their frequency response, effectively acting as low-pass filters and passing frequencies of up to only 4 to 6
khz. Many auditory displays or warnings currently used or recently designed for military use are also tonal or band-limited in nature (Patterson, 1985, 1989).
Pure-tone threshold improvements in each individual tone (0.25, 0.5, 1, 2, 4, and 8
kHz) were recorded.
Standardowo tlumienie dzwieku ochronnikow sluchu wyznacza sie jedynie dla ograniczonego zakresu czestotliwosci (od 63 Hz lub 125 Hz do 8
kHz) [15,16].
New X-Press 15
kHz from Sonics 8< Materials, Inc., Newtown, Conn., is said to offer more power and amplitude than the company's X-Press 20
kHz.
Although speech contains a wide range of frequencies [4], according to Ardoint and Lorenzi [5], the most important frequency range in terms of speech perception is 1-2
kHz. Usually, the SNHL begins at high frequencies and slowly spreads to lower frequencies.
