  • Threshold Noise Levels
    Threshold Noise Levels
    Young, Murray F. ;
    Woods, Donald L.
    1970-12-01 | PDF
    Human tolerance to noise levels created by vehicular traffic has been examined. A review of available literature indicated that there are numerous suggested maximum highway noise levels, although general consensus indicates that for a noise beyond 70 dBA, complaints are likely. Most investigations pertain only to daytime noise levels; therefore, it ...

    A device and method for rapid indirect measurement of human systolic and diastolic blood pressures.
    Lategola, Michael T. ;
    Harrison, Hiley F.
    1970-12-01 | PDF
    An indirect blood pressure measuring device and method were evolved for human use. This system is capable of providing 30 measurements each of systolic and diastolic pressures per minute. The system utilizes two brachial blood pressure cuffs (one on each arm) and fully automatic cycling for each pressure measurement. The main advantages of this sys ...
