The songs of Chinese bulbul showed smaller dialect systems among the 3 different environment noise habitats. The smaller dialect systems might be resulted from fragmented habitats. For transmitting messages successfully, Chinese bulbul contending with masking of anthropogenic noise by the higher minimum frequency, the lower maximum frequency, and the narrower band in the urban area.

Most of the frequency（1455.99 ± 187.09 Hz to 3534.13 ± 301.53 Hz）of songs in Chinese bulbul are overlapped with environment noise（under 3000Hz）. In order to study the impact of urban noise on the song performances of Chinese bulbul, this study was carried out at Taichung urban areas focusing on the difference of dialects between different environment noise habitats（Shu Yi Area, Chung Hsing University, Taichung Metropolitan Park） from March to November 2007. In addition to the 3 study sites, I sampled another 6 sites （Fengle Park, Taichung Park, Botanical Garden, Art Boulevard, Ren De Village, Tong Lin Village）to find out the differences of songs frequency resulted from different environment noise habitats.

The results of empirical research indicates that: Nonrecurring gains have a significant positive impact on the stock price, instead nonrecurring losses don't have a significant impact on the stock price; Nonrecurring gains and losses have an obvious information noise, and nonrecurring losses have greater information noise than nonrecurring gains; Nonrecurring gains and losses of the listed companies when the absolute value of more than 10% of the return of extraordinary items have greater information noises than the companies which has the absolute value of less than 10% of the return of extraordinary items.

Plate and λ/2 plate were placed inside the Nd∶YVO4KTP green laser cavity with angle 90°between their fast axis.The composite plate composed of HWP,QWP and KTP has the function of QWP.The composite plate with Nd∶YVO4 can effectively suppress the coupling of polarized modes,and multi-longitudinal-mode lownoise green laser was obtained.Since the composite plate counteracted the phase shift induced by temperature sensitivity of quartz plate,the green laser operated with lownoise reliability in different output power and different operation temperature.The threelongitudinalmode, the noise of less than 0.5% and output power stability of less then 1% for 12 hour are obtained in the green laser.

The study also evaluates the effects of FbAANC headset on speech intelligibility on a disyllabic Mandarin word discrimination test platform. We expect someone under the noisy environment in SNR equal 0,–5,–10,-15,-20 and –25 dB, the noise cancellation technique could either improve the speech discrimination effectively. Finally, the SNR below -10dB, the mean WDT score with FbAANC headset was superior to without FbAANC headset 13 to 32% through 30 subjects of normal hearing threshold for evaluation. These results suggest that the FbAANC headset would be useful for hearing protection in workplaces with high levels industrial noise.

After the cut-off frequency has been determined, the active noise-filtered system can be designed with several circuits to filter out those frequencies higher than the cut-off frequency and reserve the speech voice only. Besides, the music signals from the MP3 or a CD player can also be transmitted to the earplug system for increasing the signal noise ratio. The anxiety and tension of patients during treatments can, thus, be relaxed due to the euphonious music and toothaches of the patient might be further reduced.
