The system consists of the nano-resolution pressure transducer Model 6000-16B manufactured by Paroscientific Inc., USA and pressure hoses (flexible polyvinyl chloride product) for reducing wind noise. Field tests were made at Isumi, Japan (IS30), one of the CTBT infrasound monitoring stations. As a result, the noise level at the frequency range from . to Hz was found to be on the order of 10-2-10-3 Pa when the wind speed was less than 0.2 ms-1. The wind noise reduction system indicated similar performance with the stainless pipe array employed in the CTBT monitoring system even in the strong winds reaching 8.0 ms-1. Comparison with the microbarometer Model MB2000 manufactured by Martec Tekelec Systemes, France in the frequency domain confirmed that the two sensors produce almost identical spectra above 0.02 Hz. The portable system was then installed at the Kurokami-Seto station of Japan Meteorological Agency near Mt. Sakurajima, which is now exploding frequently at the Showa crator. Comparison with the microbarograph Model MB2005 (successor of MB2000) again confirmed that our system is able to record the infrasonic signals from volcanic explosions in the wide frequency band up to 10 Hz.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"＜論説＞","subitem_description_type":"Other"},{"subitem_description":"通常投稿","subitem_description_type":"Other"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"71586","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MURAYAMA,
