The maximum sound pressure level standards of Beijing Olympic Organizing Committee is introduced.
Finally figures of direction coefficient of sound pressure level are given out. Then using these figures the relationship between sound power level and sound pressure level radiated by a fan in...
For level instruments required to send signal remotely, diaphragm sealed differential pressure level transmitter, displacer transmitter and radar transmitter shall be selected.
And stepwise regression analysis demonstrates that BMI and the diastolic blood pressure level, the exercise situation show correlation.
This simple treatment also rationalizes the observed insensitivity of burning rates to chemical factors and pressure level.
It is necessary to protect the ear to reduce sound pressure on it if the ear is to be subject to noise at a sound pressure level more than 85 decibels continuously.
The protection of the ear to reduce sound pressure on it is necessary if the ear is to be subjected to noise at a sound pressure level more than 85 decibels continuously.
Zhang Yuting: it is important to calculate the patient's risk, perhaps a 10-year risk, with the baseline characteristics of their blood pressure level.
Higher sound pressure level (SPL) favored both collision efficiency and agglomeration kernel, so acoustic agglomeration increased in the higher-intensity acoustic field.
Under the same frequency and same sound pressure level, the infrasound damage on the brain didn't show linear correlation with the acting time of infrasound.
If the toy has a clearly defined operating cycle, measure the time average (the equivalent continuous) sound pressure level in each microphone position during at least one whole cycle.
So some developed countries with external thermal insulation layer flat, and allowed to use iron float shall be used to beat, can only use wood float shall be used to rub pressure level off.
Fan noise has been used in telephone booths to mask speech interference from adjacent booths. Usually, the problem is how to reduce the sound pressure level, either at source or on the transmission path.
It is also designed to withstand high sound pressure levels.
