We’re back online with the new World Hum Map 3.0. www.thehum.info

Apparently the Chrome Browser is rendering things a bit strangely sometimes. What a great opportunity to dump it and start using what is far and away my favourite, The Brave Browser – private, full-featured, and ultra-fast. I have no relationship or connection whatsoever with the company.

The new Hum Map 3.0 Website is being uploaded – the site will be down for up to 24 hours

Finally, the March 2022 World Hum Map Update

Two quotes set the stage for this post.

First, “If you are unhappy with your volunteers’ work, cut their pay in half” – Anonymous

Second, “Customers never remember a delayed meal, but they always remember a bad meal” – Chef Marco Pierre White

The delay on this update falls somewhere between a crime and a scandal, but it has arrived. As time permits, I and other volunteers will take second and third looks at the new points to ensure their validity and quality, and fresh statistics will be generated.



Looking for a last bit of technical help to finish a significant update to the Hum Map.

I’m swamped with teaching right now and I wouldn’t mind passing on a task to somebody. If you know something about MySql and can do basic tasks with it, I need help tweaking a column or two in order to make the Google Forms input match the database that drives the Hum Map. Let me know if you can help. glen.macpherson@gmail.com

The World Hum Map has been updated

Thank you to Henrik for his careful filtering of the raw data, and to Jason Lewis for his programming assistance on this one.

We’ve added just over 600 high quality data points to the World Hum Map. I’ve enlisted the help of a SFU Psychology student in generating the new statistics for Hum Hearers, and one early result is that we know the mean and median ages of Hearers are 43 and 45 respectively. I’ll release the full set of statistics when they are ready.

Technical Assistance Required (MySQL and geocoding)

The latest Hum Map update (the first in a long time) is waiting to be published, but the new 600+ Hum reports in the database are not geocoded and therefore are not appearing on the Map. If you know how to geocode an address column in a MySQL table, then please contact me. Note: addresses are from around the world.



Vanessa Lowe has done an excellent piece on the Hum

With all the low-quality stuff out there, this one stands out – professionally produced and properly-researched.


The World Hum Project Needs Expert Assistance


Please share this widely on all your social networks. I’ve never asked for that before. The time has come to ask for specialist help in bringing the World Hum Project to its conclusion, which is to conclusively identify the source of the World Hum and then discover how to ameliorate it. I’ve helped lift this upward so far, but now it’s time for the next generation of Hum researchers to step forward. Note that it is time-consuming, brings in no profit, and subjects oneself to mild online abuse.

We need people with post-secondary credentials who can help move this project to a serious private or university laboratory where it can be quickly solved. Once that happens, I can retreat back to my previous life. I won’t quit until then.

For anybody who has a degree in History, especially Post-Industrial Revolution, we have a serious and immediate job that needs tackling that could change everything. You’ll need full-text access to the earliest Times of London.

If you work in a facility that has a 24/7 MRI, preferably an fMRI, and you have significant influence over scheduling, then we need you.

If you are a medical doctor (MD or equivalent), we need you.

If you are an expert in non-profit marketing, we need you.

If you are a medical audiologist with expert knowledge of tinnitus, your expertise would be a major push forward.

If you own high-quality recording equipment, which includes as an example the family of Zoom recorders, and you are able to use Audacity or some other sound-analysis software and you happen to be travelling around North America, then we need you.

For those who have made it this far, you should realize that the Hum Phenomenon, and this project, have appeared seriously on most of the world’s major media, and across more than 30 countries. This phenomenon has now been normalized, and serious people are becoming interested.

Let’s solve it.




I’m mildly concerned that so many people think I’m an expert on so many different things. It’s not true, of course. For the record, my expertise is in mathematics pedagogy, teacher education, and high stakes standardized testing. I am not a scientist. However, for over 30 years, I’ve taught mathematics, psychology, physics, general science, biology, and other subjects. Over the past eight years, my goal has been to bring serious and disciplined inquiry to the Hum phenomenon. A basic working knowledge in a broad number of academic fields has helped me and people I work with to make some progress in this regard.

Every week I receive a large number of emails from people around the world, most of whom want to discuss unusual sounds they have heard or are still hearing. In roughly three-quarters of these cases, they are hearing an anthropogenic noise, and I am able to help them by pointing to Henrik’s guide for tracking down environmental noise, although for some people this appears to be too much work. There are also people who write to me because they want my validation or support for their battles against wireless technologies, 5G in particular. There was indeed a point in time when I was investigating the possible role of EM energy in generating the Hum. VLF radio (3 kHz to 30 kHz frequencies) were of particular concern; we have enough evidence now to set aside that theory and move on to other explanations that better fit the data.

We may discover or confirm a few years down the road that some types of wireless energy, including 5G, have deleterious effects on living tissue. Apart from the unhinged commentary on the issue, I’ve also scanned a few seemingly serious papers that do indeed raise troubling questions. But there is absolutely no evidence that Electromagnetic (EM) or Radio Frequency (RF) energies cause the Hum. Some folks don’t want to hear this, probably because they think it means I’m somehow endorsing or enabling the widespread use of such technologies. I’m doing no such thing, but the distinction seems to be lost on some.

My advice to those who are concerned about wireless energy is to accept a few things. First, spending a couple of hours on the internet does not make you knowledgeable on a topic. Second, that scientists are among the bravest people I know, and they want nothing more than to discover the truth. There is no scientific cabal operating here. They arrive at consensus by sharing their results with their colleagues, who brutally examine and pick apart the data and logic. If experimental results can be replicated, and the claims validated, then science moves forward. Alas, far too many people today start with the conclusion that appeals to them emotionally and then they hunt for evidence or interpretations of data that fit what they have already assumed to be true. As a teacher of psychology, I am fascinated by this – that is, how intelligent and educated people can hold on to some beliefs even in the face of colossal and overwhelming evidence to the contrary. To avoid being gratuitously abrasive, I’ll refrain from listing specific examples.

I try to bring people together with enthusiasm and curiosity rather than through rhetoric, but I’ll repeat what I’ve written elsewhere. Science is arduous and challenging work, and often people’s lives are too full to take that on. Also, some people are intellectually lazy.


Thousands of people are hearing the Hum for the first time

I think there’s good evidence that large numbers of people have started hearing the Hum for the first time. One classic sign of the Hum is that it is perceived to be louder at night than during the day. The presumed reason for this is that ambient daytime noises mask the Hum, and when the noise of civilization quiets down later at night, the Hum can be much more easily noticed. The COVID-19 pandemic has provided the conditions to test this assumption. Anthropogenic noise around the world is now the quietest it has been in many decades. Air traffic, freeway traffic, and industrial activity and so on have been sharply reduced. And concurrent with this I have been flooded with emails from people who have independently searched for and found the World Hum Map and this blog. They are searching for the source of the noise that many of know all so well. It is also important to note that there are also people writing to me telling me that their hum has stopped. My hypothesis is that those people were not hearing the Hum in the first place, but rather classic acoustic noises that share similarities with the World Hum. The fact that there are far more people in the first category compared to the second, points to this conclusion. I will be very interested to analyze the data that has been reported after the first week of March 2020.

Of course, among those emails are the usual questions about the so-called “sky trumpets”, and so on. It was never my goal to determine the source of those noises, which I am sure are very ordinary, but this seems to be an unintended outcome of this project. You can find my analysis of that topic elsewhere on this blog.
