This paper focuses on whether masking signal with natural sounds is an effective way for mitigating annoyance caused by monotone-like tinnitus. Four natural sounds, pink noise, and narrow bandwidth noise were applied as maskers in the present study shown in this paper. Two monotones were applied as maskees. As a basis for research, natural sounds do not necessarily mask monotones entirely. According to the results, spring water and rain noise can be selected as effective noise for masking monotones. In the case of monotones with different frequency, the same masker performed a little differently on masking. We preliminarily demonstrated the feasibility of natural sounds for masking monotone-like tinnitus, which is of great use for improving maskers in tinnitus masking therapy.
Objective To investigate the information of label use of high-alert drugs for children of high risk population, in the Military General Hospital of Beijing PLA. Methods We selected high-alert drugs used in this hospital as objectives. The package inserts of these drugs were investigated and medication parts for children were analyzed. Results 201 drugs regarded as high-alert drugs were included, of which only 78 drugs have accurate detailed description of medication for children, accounting for 38.8% of the total of investigated high-alert drugs. Conclusion Children, as high-risk population, needs more attention concerning the use of high-alert drugs. However, risks in the use of high-alert drugs increased due to the lack of the information of label use of high-alert drugs. To ensure the safety of drug use in children, the information of drug use for children in the package inserts should be urgently supplemented.
