What causes avoidable noise in vehicles?

Several factors contribute to avoidable noise in vehicles. We focus on providing noise control solutions, like acoustic insulation materials, soundproofing technologies, and engineering services aimed at optimising vehicle acoustic performance across these various areas. These factors can originate from various sources within the vehicle and its environment. Here are some key causes of avoidable noise:

  • Engine and Powertrain Noise: The combustion process in engines and the operation of powertrains – including transmission and drivetrain components – can generate significant noise. Engine components, exhaust systems, or inadequate insulation can amplify this noise.
  • Exhaust and Intake Noise: The exhaust system and components can produce noise due to airflow and pressure. Exhaust pipes, mufflers, or ventilation systems can contribute to unwanted noise levels.
  • Road and Tyre Noise: Interaction between tyres and road surfaces generates noise, particularly at higher speeds. Specific tyre design, road surface irregularities, and inadequate sound insulation can lead to increased road and tyre noise inside the vehicle cabin.
  • Vibrations: Vibrations from an engine, drivetrain, or road surface can cause parts of the vehicle to resonate, amplifying noise. Vibrations can occur in panels, windows, and interior components if not properly dampened or isolated.
  • Electrical and HVAC Systems: Electrical components, including fans, motors, and HVAC (Heating, Ventilation, and Air Conditioning) systems, can generate noise if they are not adequately insulated.
  • Interior Trim and Components: Interior materials and components, such as dashboard, seats, and door panels, can resonate or transmit noise if they are not insulated.

What are the loudest parts of a vehicle?

In a vehicle, several components and conditions contribute to generating significant noise levels. Effective noise control measures typically involve identifying and mitigating these sources through the use of acoustic materials, insulation, damping treatments, and optimised vehicle design. Reducing noise from these loudest parts not only improves comfort but also enhances the overall driving experience and vehicle quality.

Here are some of the loudest parts and sources of noise in a typical vehicle:

  • Engine: The engine is a primary source of noise in vehicles, especially during acceleration and high RPMs. Combustion noise, mechanical vibrations, and exhaust system noise all contribute to the overall engine noise.
  • Exhaust System: The exhaust system can generate considerable noise due to the flow of exhaust gases and pressure fluctuations.
  • Tyre and Road Noise: Interaction between the tyres and the road surface generates noise, particularly at higher speeds. Tyre design, road surface condition, and vehicle speed all influence the amount of road noise transmitted into the cabin.
  • Wind and Airflow: Airflow around the vehicle can create unwanted noise, which can be significant at higher speeds. 
  • Transmission and Drivetrain: Transmission gears and drivetrain components can produce noise due to mechanical friction, gear meshing, and bearing operation, especially during speed changes.
  • HVAC System: A HVAC system includes components such as fans, blowers, and air ducts, which can generate noise when operating at higher fan speeds.
  • Brakes: Braking systems can produce noise due to friction between brake pads and rotors or drums. This noise can vary depending on braking intensity and vehicle speed.
  • Interior Trim and Panels: Vibrations and resonances in interior trim panels, dashboard, doors, walkways and seats can amplify noise from external sources or mechanical components within the vehicle.
  • Electrical Components: Motors and other electrical components in the vehicle can produce noise during operation.

What is an acceptable dB noise level in a vehicle?

In general, acceptable noise levels in vehicles can vary depending on the context and the specific area within the vehicle. Here are some typical guidelines for noise levels in different parts of a vehicle:

  • Interior Cabin: The interior cabin of a vehicle is where passengers sit, and it’s crucial for comfort and communication. Acceptable noise levels in the cabin are typically measured in terms of A-weighted decibels (dBA). Here are some guidelines:
    • At idle or low speeds: Less than 45-50 dBA is considered quiet.
    • At cruising speeds (highway speeds): Less than 65-70 dBA is considered comfortable for most passengers.
    • Peaks in noise levels (such as during acceleration or passing): Up to 80-85 dBA may be acceptable for short durations.
  • Exterior Noise (Pass-by Noise): This refers to the noise emitted by a vehicle as it passes by an observer or when measured at a certain distance from the vehicle. Regulations often dictate maximum noise levels for vehicles:
    • In many regions, passenger cars are typically required to meet pass-by noise limits around 72-75 dBA at specific speeds and distances (e.g., 50 km/h at 7.5 meters).
  • Engine Compartment: Within the engine compartment, noise levels can be higher due to the operation of the engine, exhaust system, and other mechanical components. However, efforts are made to minimize noise transmission into the cabin and ensure that noise levels are not excessive.
  • Other Areas: Noise levels in areas such as trunk compartments, underbody, and wheel wells are also considered, particularly for electric vehicles where road and tire noise might be more noticeable.

The aim in setting acceptable noise levels in vehicles is to ensure passenger comfort, minimise driver fatigue, and comply with regulatory standards related to vehicle noise emissions. We design various solutions such as acoustic insulation and sound-absorbing materials to achieve quieter vehicle conditions and comply with noise regulations.

What causes avoidable noise in the industrial sector?

In the building sector, avoidable noise can arise from various sources and conditions both within and outside of buildings. Managing these sources effectively requires understanding the factors contributing to noise generation and transmission. Addressing avoidable noise in the building sector involves implementing noise control measures during building design, construction, and occupancy phases. These measures may include the use of sound-insulating materials, acoustic treatments, vibration isolation, and appropriate placement of mechanical equipment. We provide solutions to mitigate noise and enhance comfort for building occupants, ensuring compliance with regulatory standards and improving overall quality of life. Here are some common causes of avoidable noise in the building sector:

  • Exterior Sources:
    • Traffic Noise: Noise from road traffic, including cars, trucks, and buses, especially near highways or busy streets.
    • Aircraft and Airport Noise: For buildings near airports, noise from aircraft take-offs and landings can be significant.
    • Construction and Demolition: Noise generated by construction activities such as drilling, hammering, and heavy machinery.
  • Interior Design and Layout:
    • Room Acoustics: Inadequate acoustic design within rooms, such as reverberation or sound reflection issues, can increase noise levels.
    • Flooring and Ceiling Materials: Certain types of flooring and ceiling materials may not provide adequate sound insulation, allowing noise to travel between floors and rooms.
    • HVAC Systems: HVAC systems, including fans, compressors, and ductwork, can generate noise due to airflow, motor operation, and vibration.
    • Water facilities: Water pumps, pipes, and valves can create noise from fluid flow, pressure changes, and mechanical vibrations.
    • Generators and Transformers: Electrical generators, transformers, and switchgear can emit noise from electrical operations and cooling mechanisms.
    • Human Activities: Noise generated by occupants, such as footsteps, conversations, and activities like taking meetings or audio use, can contribute to overall noise levels.

What is a noise barrier for buildings?

A noise barrier for buildings, also known as an acoustic barrier, is one of the many Industrial Noise Control products we offer. It is a specially designed structure to reduce the transmission of noise from external sources into the interior of a building or from one area to another within a building. The primary purpose of an acoustic barrier is to block unwanted noise, improving the acoustic environment on building sites, roof spaces and more.

What is environmental noise?

Environmental noise refers to unwanted or harmful noise generated from various sources in the environment. It includes noise produced by transportation (such as road traffic, railway, and aircraft), industrial activities, construction sites, recreational activities, and other human-made sources. Environmental noise can also originate from natural sources such as wind, waves, and wildlife.

What is the HSA recommended noise level for working conditions?

An employer must assess the level of noise in the workplace. If any workers are exposed to a daily personal noise exposure above 80dB (A), then appropriate measurements must be taken in accordance with the regulations and the original EU Directive i.e. carry out an occupational noise assessment.

What is the OSHA recommended noise level for working conditions?

OSHA sets legal limits on noise exposure in the workplace. These limits are based on a worker’s time weighted average over an 8-hour day. With noise, OSHA’s permissible exposure limit (PEL) is 90 dBA for all workers for an 8-hour day. It is important to note that regulations differ from country to country. Here at Ventac, we’re here to design the most comfortable environment to suit specific needs and regulations.
