Head Injuries from CNC frequency

1/9/17

New York Times has a short article (with charts for Pat) about how the brain is wired with respect to head injuries from contact sports.

All kinds of new information is showing up that wasn't around when some of us played football in high school. This information is unfolding what happens in the brain from minor bangs.

I'm wondering about the impact of CNC machines on brain wiring. They sound a lot like electronic mosquitoes and sometimes it takes a while for the ringing in your head to go away after exposure. This CNC noise isn't exactly like a knock from a football helmut but could the high frequency vibrations have a similar long-term effect on neural wiring?

Your theory is a stretch.

Somebody posted a story awhile back about ringing in your ears from hearing loss from exposure to noise.

There was also movie recently called Concussion about this.

The first time somebody suggested football caused CTE injuries the NFL also said it was a "stretch".

Be an interesting study. we know that CTE in football is pretty highly linked to drug abuse, suicide, etc. Wonder what the % is of cnc operators?

I don't see how sound can be compared to impact to the head.

The comparison is not necessarily between impacts to the head and noise from a CNC. The subdural effects, however, may be similar over time.

The navy is doing a lot of research about the impacts of high frequency sounds on marine mammals. This may or may not have any implication with respect to mammals in a cabinet shop.

Noise sneaks up on you. Best to pay a lot of attention and wear the best headphone equipment you can get, particularly around these electronic mosquitoes.

As per Occam's Razor I would be more concerned about what we breath as woodworkers. Followed by what we ingest because of pesticides on our food. Preceded, by stress in general, is not healthy.

"Somebody posted a story awhile back about ringing in your ears from hearing loss from exposure to noise."

It's called tinnitus and it's a very real issue.

I spent 20 years mixing live sound for rock bands and used hearing protection when I wasn't actually mixing. I had my ears insured and tested every year. I always passed well enough to keep my insurance.

When I moved back into woodworking I never considered the whine of saw blades and machinery as dangerous for some reason and less than ten years later I had tinnitus bad. There is no known cure or treatment, I will have sirens in my ears for the rest of my life.

Save your hearing,
WEAR HEARING PROTECTION IN THE SHOP AT ALL TIMES!

What Jeff said, hearing protection. Just wear it!

What Jeff and Jay said.

Wear protection on your ears......and not just foam plugs when near the CNC. High quality over the ear protectors are your best bet.

    FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards (return to top)

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.
  • Comments, questions, or criticisms regarding Forum policies should be directed to WOODWEB's Systems Administrator

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk. WOODWEB reserves the right to delete any messages it deems inappropriate. (return to top)
