Noise Consultant

If you’ve been to your doctor’s office lately, you might have been allowed to listen to a conversation between a doctor and another patient. You didn’t even need to be in the room with them. The sound isolation between many exam rooms can be so poor that you can hear virtually everything that is said […]




We were recently called in to help with controlling the noise levels at an engine test facility. I went to the site to take noise measurements in various areas of the facility. The problem was not within the test cells, but from all the external equipment needed to run the cells from air compressors, to […]




Good communication can be difficult, especially over long distances. This is why we still get on airplanes and travel to meet face to face. Videoconferencing saves the travel costs, and it still gives us the face to face connection. But here’s the key: the videoconference environment itself is critical to ensuring communication success. Human ability […]




“Wow, you guys are expensive”. I’ve heard this once or twice so far in my career. Interestingly, I hear it the most from industrial and manufacturing clients where employee noise exposure is a major issue in their operations. It’s true, the consulting fee can be a little overwhelming at first, however, if you step back […]




Recently, I visited a healthcare facility to talk with them about oral privacy related to HIPAA privacy requirements. As we toured the facility they shared the following story: A patient came in and was shown to the exam room and told that Doctor X would be in soon. After about 5 minutes, the patient returned […]




Most parents will tell you that they just wish they could understand why their baby is crying. As cute as babies are, the reality is they can be immensely distracting during church worship services. So what can you do about it? Acoustics By DesignAcoustics By Design consultants provide acoustical consulting services to architects, engineers, facility […]




Being a noise engineer, I’m always on the “listen-out” for cases of poor building acoustics. I find that common offenders are noisy air handling (HVAC) systems. Frequently the public venues are restaurants, hotels and cinemas, and on occasion it’s a location most tragic, a performance space. HVAC noise in a performance space distracts listeners and […]




Over the years we’ve used this blog to try and get the word out that acoustics can be very important when designing a restaurant and that the assistance of a qualified acoustical consultant during the design phase will save the proprietor both time and money while ensuring the ambience is top notch. So just how […]




The LEED® green building certification program gives out points for naturally ventilating buildings, and it also gives out points for acoustics – especially for low levels of background noise levels. As the industry is finding out, naturally ventilated buildings create more opportunities for buildings to be penetrated by exterior noises, thus creating unintended loud background […]




Several weeks ago, a client invited me to a rehearsal in their highly reverberant space that ABD was hired to test and correct. I declined, as I already had plans to attend a play that evening at a different facility, and joked that during the performance I’d also be listening to sirens from the main […]




The 2010 FGI Guidelines for Design and Construction of Health Care Facilities was published in January and adopted as building code by many states. How will you deal with the new noise, privacy, and acoustical requirements for healthcare facilities? Join us at SoundHealthcare 2010, a Health Care Acoustics Seminar, and find out what you must […]




For many of our larger projects, we offer Acoustical Consulting Construction Administration Services as an additional option. Unfortunately, not all clients invest money on this service. Our frustration extends well beyond the revenue side of the project (the CA services are usually a very reasonable addition to the project budget, relative to Design Services). Sometimes […]




January 2010 held a highly anticipated milestone for acoustical consultants. The definitive guide called 2010 FGI/ASHE Guidelines for Design and Construction of Health Care Facilities has a greatly expanded acoustics section in this year’s edition. How will you deal with the new noise, privacy, and acoustical requirements for healthcare facilities? Join us at SoundHealthcare 2010, […]




So what in the world are anechoic chambers? In short, they are the consultant’s and manufacturer’s best friend when it comes to acoustics. Anechoic chambers are primarily used for a variety of acoustical measurements that determine just how much noise a product is making. These chambers are most notable for their strange appearance… their foam […]




Industrial plants are most often loud and dynamic work environments. Noise fields are complex with varying levels of noise produced by many different pieces of equipment, and employees spend varying amounts of time near the different noise sources. Sound levels are even impacted by the building, with taller spaces generally quieter than single story spaces, […]




Hospitals and Healthcare Facilities have requirements for large volumes of ventilation and strict control of airflow, and the greater the airflow, the greater the potential for noise. Building mechanical services equipment, fans, pumps, cooling, and heating equipment are all sources of high noise levels. When Acoustics By Design works on a new hospital, we typically […]




On a recent trip to Chicago, my wife and I were thankful for all the new traffic lanes recently completed. I can remember when the trip back home to my folks took an extra couple of hours if I got stuck in all the traffic. But thankfully, with the new highway renovations, we’ve actually had […]




Who Can See the Wind? (by Christina Georgina Rossetti) Who can see the wind? Neither you nor I But when the leaves are trembling The wind is passing by! Who can see the wind? Neither I nor you But when the trees are bending low The wind is passing through! As this children’s poem points […]




For today’s topic, let’s think of driving our car with the wind rushing by, when all of a sudden our attention is drawn by that annoying squeak coming from the dashboard. The changing of the squeak with time was the topic of a recent blog, but this time we’ll examine its tonal nature. Acoustics By […]




From mega-churches to small town congregations, the video-venue concept is becoming a staple of church growth. For those not “in the know”, a “video-venue” is a church meeting where parts of the service (typically the sermon or message) are piped in via video signal and projected on a large screen, while other parts of the […]
