It’s more important than ever before to ensure work environments are conducive. It helps with wellbeing, performance, job satisfaction, retention, and recruitment. There is a lot to think about, including ambient noise levels, layouts, and the temperature. We want to have a closer look at sound here and how to use an attenuator to address ventilation noise. So, read on to learn more, then speak to us if you need fantastic solutions.
Acoustic goals
One of the most important things to keep in mind is every workplace is unique. As a result, the acoustic goals will be too. You need to think carefully about what you want to achieve. For example, is the aim to reduce noise in a very loud factory, warehouse, or chemical manufacturing plant?
A key thing you need to look at is the ventilation system. They will also be unique, depending on the layout of the property, location, and HVAC requirements. You must consider the type of system, airflow requirements, turbulence, and the noise level. If you understand all the nuances here, you can design the ideal solutions to tackle HVAC noise.
The solution
In many cases, a splitter ventilation attenuator will be the best solution. They have the potential to dramatically reduce the amount of noise. You need a bespoke design for each particular building though.
You may be wondering how attenuators work to achieve acoustic goals. It is actually really interesting. Unlike other solutions like enclosures and blankets that block sound, an attenuator reduces noise by turning some of the sound energy into heat. They do this by using baffles or splitters with cores of acoustically absorbent material, often rock wool or fibreglass.
There are a number of details to think about if you are designing ventilation attenuators. Firstly, you need to consider how many splitters or baffles you need. Secondly, you need to look at the splitter or baffle designs. In many cases, longer attenuators are better. If you have high frequency noise, you will need thinner baffles or splitters. With low frequency noise, you need the opposite.
You can’t focus too much on the acoustic goals here though. Remember that introducing any equipment into HVAC systems, including attenuators, will have an impact on airflow. If you get it wrong, it can have a negative effect. Ideally, your design should reduce noise as much as possible without a noticeable reduction in airflow.
