The acoustics research team in the Department of Physics and Astronomy at Brigham Young University has put Spectrum's leading digitizers and signal generators at the heart of its new underwater acoustics lab. The lab simulates a miniaturized version of the ocean environment, enabling a wide range of experiments on the behavior of sound waves in different layers of water and how they are reflected in the ocean's most sampled surface materials, such as rock, sand or mud. Such miniaturized experiments require a high degree of precision in the measurement equipment in order to magnify the results to a realistic scale.<\/p>","protected":false},"author":33,"featured_media":23750,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_eb_attr":"","ocean_post_layout":"","ocean_both_sidebars_style":"","ocean_both_sidebars_content_width":0,"ocean_both_sidebars_sidebars_width":0,"ocean_sidebar":"0","ocean_second_sidebar":"0","ocean_disable_margins":"enable","ocean_add_body_class":"","ocean_shortcode_before_top_bar":"","ocean_shortcode_after_top_bar":"","ocean_shortcode_before_header":"","ocean_shortcode_after_header":"","ocean_has_shortcode":"","ocean_shortcode_after_title":"","ocean_shortcode_before_footer_widgets":"","ocean_shortcode_after_footer_widgets":"","ocean_shortcode_before_footer_bottom":"","ocean_shortcode_after_footer_bottom":"","ocean_display_top_bar":"default","ocean_display_header":"default","ocean_header_style":"minimal","ocean_center_header_left_menu":"0","ocean_custom_header_template":"0","ocean_custom_logo":0,"ocean_custom_retina_logo":0,"ocean_custom_logo_max_width":0,"ocean_custom_logo_tablet_max_width":0,"ocean_custom_logo_mobile_max_width":0,"ocean_custom_logo_max_height":0,"ocean_custom_logo_tablet_max_height":0,"ocean_custom_logo_mobile_max_height":0,"ocean_header_custom_menu":"0","ocean_menu_typo_font_family":"0","ocean_menu_typo_font_subset":"","ocean_menu_typo_font_size":0,"ocean_menu_typo_font_size_tablet":0,"ocean_menu_typo_font_size_mobile":0,"ocean_menu_typo_font_size_unit":"px","ocean_menu_typo_font_weight":"","ocean_menu_typo_font_weight_tablet":"","ocean_menu_typo_font_weight_mobile":"","ocean_menu_typo_transform":"","ocean_menu_typo_transform_tablet":"","ocean_menu_typo_transform_mobile":"","ocean_menu_typo_line_height":0,"ocean_menu_typo_line_height_tablet":0,"ocean_menu_typo_line_height_mobile":0,"ocean_menu_typo_line_height_unit":"","ocean_menu_typo_spacing":0,"ocean_menu_typo_spacing_tablet":0,"ocean_menu_typo_spacing_mobile":0,"ocean_menu_typo_spacing_unit":"","ocean_menu_link_color":"","ocean_menu_link_color_hover":"","ocean_menu_link_color_active":"","ocean_menu_link_background":"","ocean_menu_link_hover_background":"","ocean_menu_link_active_background":"","ocean_menu_social_links_bg":"","ocean_menu_social_hover_links_bg":"","ocean_menu_social_links_color":"","ocean_menu_social_hover_links_color":"","ocean_disable_title":"default","ocean_disable_heading":"default","ocean_post_title":"","ocean_post_subheading":"","ocean_post_title_style":"","ocean_post_title_background_color":"","ocean_post_title_background":0,"ocean_post_title_bg_image_position":"","ocean_post_title_bg_image_attachment":"","ocean_post_title_bg_image_repeat":"","ocean_post_title_bg_image_size":"","ocean_post_title_height":0,"ocean_post_title_bg_overlay":0.5,"ocean_post_title_bg_overlay_color":"","ocean_disable_breadcrumbs":"default","ocean_breadcrumbs_color":"","ocean_breadcrumbs_separator_color":"","ocean_breadcrumbs_links_color":"","ocean_breadcrumbs_links_hover_color":"","ocean_display_footer_widgets":"default","ocean_display_footer_bottom":"default","ocean_custom_footer_template":"0","iawp_total_views":40,"ocean_post_oembed":"","ocean_post_self_hosted_media":"","ocean_post_video_embed":"","ocean_link_format":"","ocean_link_format_target":"self","ocean_quote_format":"","ocean_quote_format_link":"post","ocean_gallery_link_images":"off","ocean_gallery_id":[],"footnotes":""},"categories":[2357],"tags":[1733,1786,1788,1789,1787],"table_tags":[],"class_list":{"0":"post-23674","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","6":"hentry","7":"category-pxi-pxie","8":"tag-spectrum","10":"tag-1788","11":"tag-1789","12":"tag-1787","13":"entry","14":"has-media","15":"owp-thumbs-layout-horizontal","16":"owp-btn-normal","17":"owp-tabs-layout-horizontal","18":"has-no-thumbnails","19":"has-product-nav"},"aioseo_notices":[],"jetpack_featured_media_url":"https:\/\/hongtronics.com\/wp-content\/uploads\/2022\/09\/Pic1_water_tank_web-696x522-1.jpg","_links":{"self":[{"href":"https:\/\/hongtronics.com\/en\/wp-json\/wp\/v2\/posts\/23674","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hongtronics.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/hongtronics.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/hongtronics.com\/en\/wp-json\/wp\/v2\/users\/33"}],"replies":[{"embeddable":true,"href":"https:\/\/hongtronics.com\/en\/wp-json\/wp\/v2\/comments?post=23674"}],"version-history":[{"count":3,"href":"https:\/\/hongtronics.com\/en\/wp-json\/wp\/v2\/posts\/23674\/revisions"}],"predecessor-version":[{"id":23753,"href":"https:\/\/hongtronics.com\/en\/wp-json\/wp\/v2\/posts\/23674\/revisions\/23753"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/hongtronics.com\/en\/wp-json\/wp\/v2\/media\/23750"}],"wp:attachment":[{"href":"https:\/\/hongtronics.com\/en\/wp-json\/wp\/v2\/media?parent=23674"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/
