Identifying noise sources within these vehicles can be challenging and consideration needs to be given to both internal and external noise sources, as well as structural and air borne noise.[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/3″][/vc_column_inner][/vc_row_inner][/vc_column][/mk_page_section][vc_row fullwidth=”true” css=”.vc_custom_1531758542166{margin-top: 0px !important;margin-bottom: 0px !important;border-top-width: 0px !important;border-bottom-width: 0px !important;padding-top: 0px !important;padding-bottom: 0px !important;}” el_class=”overflow_allow landing-grey-box”][vc_column width=”11/12″ css=”.vc_custom_1531758809646{margin-top: -20px !important;padding-top: 60px !important;}” el_class=”pb-150″][vc_row_inner][vc_column_inner width=”2/12″][/vc_column_inner][vc_column_inner el_class=”top-left-square-outter” width=”5/12″ css=”.vc_custom_1531136914139{background-color: #d1d1d1 !important;}”][vc_column_text el_class=”landing_coverage” css=”.vc_custom_1531137067931{margin-bottom: 0px !important;}”]

External Noise

The noise radiating from a vehicle into the surrounding environment can affect people and noise sensitive locations. It can be expressed as a sound power level which calculates the sound energy emitted independent of its environment.[/vc_column_text][/vc_column_inner][vc_column_inner width=”5/12″ css=”.vc_custom_1531136825321{background-color: #d1d1d1 !important;}”][vc_column_text el_class=”landing_coverage” css=”.vc_custom_1531137057405{margin-bottom: 0px !important;}”]

Internal Noise

The noise levels in the passenger compartment of the vehicle including the driver’s position. For commercial vehicles, the level at the drivers location in particular is subject to the health and safety regulations for noise in the workplace .[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_row_inner][vc_column_inner width=”2/12″][/vc_column_inner][vc_column_inner width=”5/12″ css=”.vc_custom_1531136833465{background-color: #d1d1d1 !important;}”][vc_column_text el_class=”landing_coverage” css=”.vc_custom_1531137732083{margin-bottom: 0px !important;padding-bottom: 26px !important;}”]

Airborne noise

This noise path is the direct transmission of sound energy through air. The resistance of a vehicle’s partition to this energy is dependent on its physical properties and the frequency characteristic of the noise (low, medium, high).[/vc_column_text][/vc_column_inner][vc_column_inner width=”5/12″ css=”.vc_custom_1531136829500{background-color: #d1d1d1 !important;}”][vc_column_text el_class=”landing_coverage” css=”.vc_custom_1531137024646{margin-bottom: 0px !important;}”]

Structureborne noise

This is a noise pathway for noise where the energy from a source transmits as vibration along a rigid structure. This energy can cause a panel to radiate the energy as noise. If the dimensions of the panel coincide with the wavelength of the sound energy the resulting resonance can exacerbate the issue.[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][mk_page_section bg_image=”https://ventac.com/wp-content/uploads/2018/04/ventac_landing_page_row.jpg” attachment=”fixed” bg_position=”center center” bg_repeat=”no-repeat” bg_stretch=”true” full_width=”true” padding_top=”0″ padding_bottom=”35″ el_class=”overflow_allow” sidebar=”sidebar-1″][vc_column][vc_row_inner el_class=”acoustic-lab-bg”][vc_column_inner width=”2/12″][/vc_column_inner][vc_column_inner width=”5/12″ css=”.vc_custom_1531137569305{padding-top: 45px !important;}”][vc_column_text el_class=”white_text” css=”.vc_custom_1531137858693{margin-bottom: 0px !important;}”]

Acoustic Laboratory

[/vc_column_text][vc_column_text el_class=”white_text” css=”.vc_custom_1537373430821{margin-bottom: 0px !important;padding-bottom: 35px !important;}”]Acoustic laboratories are a vital resource for the development of material composites and product solutions for the vehicle noise control sector. Ventac’s acoustic laboratories are used in identifying noise issues within vehicles at their source in order to effectively and quickly design and manufacture an acoustic solution.

The acoustic laboratory includes a suite of reverberation chambers, where these materials and products can be tested for sound absorption, airborne sound transmission loss, sound reduction index and insertion loss. The sound power level of noise sources can also be tested. Noise source identification techniques include sound intensity, nearfield holography and beamforming and can be used in understanding the complex noise sources within vehicles.[/vc_column_text][/vc_column_inner][vc_column_inner width=”5/12″][vc_empty_space height=”95px” el_class=”desktop-only”][vc_column_text el_class=”white_text” css=”.vc_custom_1531137651374{margin-bottom: 0px !important;padding-bottom: 62px !important;}”]Our labs are also used to test different materials to identify how they absorb noise and energy, while also considering the manufacturers demands including low-weight, thermal and fluid resistance.

Noise kit prototyping and the development of noise reduction solutions to support different design options is supported by our adjacent manufacturing facilities. An important concern for passenger vehicle manufacturers is often designing a prototype of a material that will reduce noise, while at the same time not weighting down the vehicle or driving up fuel consumption. The Acoustic Lab can support in this product development.[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_row_inner css=”.vc_custom_1531137679067{margin-top: 35px !important;}”][vc_column_inner width=”2/12″][/vc_column_inner][vc_column_inner width=”5/12″][vc_single_image image=”27786″ img_size=”full”][/vc_column_inner][vc_column_inner width=”5/12″][/vc_column_inner][/vc_row_inner][/vc_column][/mk_page_section][vc_row fullwidth=”true” el_class=”overflow_allow high-z”][vc_column width=”2/3″][/vc_column][vc_column width=”1/3″ el_class=”no-padding”][vc_single_image image=”27243″ img_size=”full” el_class=”overflow_allow” css=”.vc_custom_1531135396996{margin-top: -115px !important;margin-bottom: 0px !important;}”][/vc_column][/vc_row][vc_row fullwidth=”true” equal_columns=”true” el_class=”overflow_allow”][vc_column width=”2/3″ el_class=”top-right-square-outter thick-padding-lr”][vc_column_text css=”.vc_custom_1531137956994{margin-bottom: 0px !important;}”]

Acoustic Camera

[/vc_column_text][vc_column_text css=”.vc_custom_1537373469672{margin-bottom: 0px !important;}”]Acoustic camera technology can also be beneficial when bringing a new vehicle to the market. An acoustic camera is made up of an array of microphones and a camera that can visualise and identify the characteristics of noise sources. Through the use of the acoustic camera, you can visually show customers the noise source and its path through their vehicle.

The mapping technology of the acoustic camera can be used to identify weak points and sound hotspots within a vehicle, while also providing an insight into the behaviour of the sound. This is done by using the phase data (wave motion) to animate the maps to show how the sound propagates from a structure.[/vc_column_text][/vc_column][vc_column width=”1/12″][/vc_column][vc_column width=”3/12″ css=”.vc_custom_1531135505840{border-bottom-width: 5px !important;border-bottom-color: #fc9933 !important;border-bottom-style: solid !important;}”][/vc_column][/vc_row][vc_row css=”.vc_custom_1531136560645{margin-top: 85px !important;}”][vc_column width=”2/3″][vc_column_text css=”.vc_custom_1531135711856{margin-bottom: 0px !important;}”]Through the use of an acoustic camera, the exact noise source can be identified, allowing vehicle manufacturers to apply the most effective acoustic solution.[/vc_column_text][/vc_column][vc_column width=”1/3″][/vc_column][/vc_row][vc_row][vc_column width=”1/2″][vc_text_separator title=”Before” title_align=”separator_align_left” align=”align_right” color=”custom” accent_color=”#fbb03b”][vc_single_image image=”27851″ img_size=”full” alignment=”center”][/vc_column][vc_column width=”1/2″][vc_text_separator title=”After” title_align=”separator_align_left” align=”align_right” color=”custom” accent_color=”#fbb03b”][vc_single_image image=”27852″ img_size=”full” alignment=”center”][/vc_column][/vc_row][vc_row css=”.vc_custom_1531303237640{margin-bottom: 35px !important;}”][vc_column][vc_column_text css=”.vc_custom_1531136123678{margin-bottom: 0px !important;}”]Ventac has an on-site Innovation and Acoustic Laboratory and has Ireland’s only commercial acoustic test chambers.
