Macbook Pros/laptops - questions about speakers, etc.

[Guest guest]

Hi,

Yesterday, I was in the Apple Store again, looking at Macbooks (I know - don't

ask). I was trying to compare the 13 " Macbook Pro and the 15 " Macbook Pro on a

few features - among them being how " symptomatic " each made me feel. I'm not

100% sure of this, but it seemed that I could " feel " whatever " spirits " were

coming from the 15 " more - which I guess is not surprising. Besides being

bigger, having a more powerful processor & graphics card and all that - I also

noticed that it seemed to have more powerful/bigger speakers inside of the

chassis. I could put my hand on the right side of the body (to the right of the

trackpad), and could feel the speakers vibrating as a YouTube video played. I

didn't feel any such vibrations on the 13 " .

I haven't come across anything really definitive - but from what I've seen via

Google, the 15 " Macbook Pro does indeed have bigger/ " better " /more powerful

speakers - with some sort of subwoofer (although the subwoofer may be small).

My question is - would the speakers contribute to any emr or emf? Could these

speakers contribute to any discomfort an electrosensitive may feel?

I remember Eli referring to how bad the Macbook Pro's AC magnetic field is -

could its speakers contribute to this field?

Also, would someone be able to feel the difference between a 15 " Macbook Pro

with a 2.4 GHz processor (Core i5) and a 15 " Macbook Pro with a 2.53 GHz

processor (also Core i5) - while doing ordinary things like websurfing, watching

YouTube? I couldn't compare these two Macbooks because only the 2.53 GHz

version was on display. Maybe the 2.4 GHz is a little better, I don't know.

I really prefer a laptop with a 15 " screen size - but for Macbooks, you have to

*pay* in a lot of ways to get this screen size.

I also repeated the AM radio test - and again, the Macbooks tested remarkably

well. The radio picked up nothing - not even when I dimmed the screens. And

this was a different Apple Store than the one where I did the previous AM tests

at.

That's amazing about the AM radio test. Conceivably they have

moved all the frequencies above 1.7 MHz. Should try an AirBand

radio. Or the MFJ-856. (mfjenterprises.com). I've heard there is

some engineer at Apple who is EHS. Maybe they've seen the light

(but I doubt it; the unibody mac book I have used (~2 years old) is

terrible.

2.4 GHz is the same as a microwave oven, and wi-fi. It might be

wise to stay away from that frequency unless you have found

(remarkably) that those don't bother you. Also a lot of cordless phones

use that frequency.

Speakers can be a factor. They have coils and usually some RF gets to them

despite the filters. Subwoofers are usually the worst.

My Acer 26 " monitor has very wide and high peaks at around 4.5 MHz.

There's something wrong with your AM radio test.

I detect plenty of noise from my brother's 17 "

MacBook Pro with an i7 processor. That machine is

lethal.

That's what I was thinking - that it's possible that the emitted frequencies are

beyond the range where a basic AM radio could detect. But I don't have the

money to spend on higher-tech, more capable sensors. Unless those radios you

mentioned are sufficiently inexpensive...

Could it also be that Apple dims their monitors by increasing the " black level " ,

instead of dimming the backlight? I've recently noticed that many LCD TVs on

the market have separate " Backlight " and " Brightness " controls - so that it's

possible to lower the brightness of the TV without messing with the backlight

(thus saving us from the emf-producing " chopping " mechanism). Maybe Apple

employs technology along the same lines?

I'm not really sure if the frequency of the processor affects me - I mean, it's

totally possible, but it could be other things about a laptop that factor more

into my sensitivity. Four or so years ago, I bought a 5.8 GHz cordless phone

system (w/ base station & remote handset) for our home, and to this day I've

never really " felt " it or have had any overt problems with it. (Maybe because

I'm not on the phone that much?) I didn't even " feel " our old WiFi (Comcast) -

unless I got very close to the router.

I could be rationalizing, though. For someone like me - who needs the assurance

of technical support options - there is little choice out there but Dell and

Apple. And I thought Apple would have the advantage over most PCs anyway -

because their operating system is less " bloated " and is custom fit for the

hardware, and would be less taxing on the hardware (making the hardware not work

as hard and making the hardware less likely to " heat up " ). And, of course - PCs

are more prone to viruses, malware - and both viruses/malware and the software

used to combat them can be taxing on the hardware. The less hard a computer has

to work, the less emr, right? Or is it that simple? Please correct me if I'm

wrong - because my current line of thinking is that even if a certain PC is

" more comfortable " than a Mac when new - it may not remain that way as the

different " issues " (malware, bloated antivirus software, etc.) accumulate over

the years.

There seem to be fewer and fewer options out there for " slower " processors -

unless you get a small netbook, or take a risk on a used computer. Apple uses

slower processors in their Macbook Airs - but the Airs screens are smaller than

I would like and from my experience, Macbook Airs aren't necessarily better for

me from an e.s. standpoint.

And from my experience with my Dell laptop - there seems to be a direct

relationship between how hot the laptop gets and how severe my symptoms are.

(I've found that just elevating the laptop so that there is more space between

its bottom and the table has given me some relief - I can feel the effects

almost immediately.) I found this website that incorprates temperature

measurements in their reviews of many laptops - and, according to this site, the

Macbook Pro has some of the coolest temperatures on the market - at least along

its top surface. It does tend to get hotter (relative to some other laptops)

along its bottom - but, to me, that might be a good thing. It signals that the

laptop is designed so that the heat " sinks " toward the bottom instead of

remaining on the surface or escaping through the top - where I am more likely to

" feel " it. If I elevate the laptop or get one of those laptop " cooling " stands

that might serve as an additional " heat sink " , it might make things (even)

better.

Here is the site that gives laptop temps - they reviewed the Core i7 version of

the Macbook Pro, so the Core i5s might be even cooler:

Hi Eli - I don't think there's anything wrong with my AM radio test. Just a few

weeks ago, I was in Sears (again) " testing " LCD TVs, and my radio picked up some

noise on at least one of the two products I was testing. And just now, my radio

picked up noise on this Dell.

My radio is the recommended Radio Shack model (CAT NO. : 12-586).

Which i7 does your brother have - I think you can get up to a 2.8 GHz i7 in a

Macbook, IIRC (particularly with the 17 " model).

I wish Apple offered more flexibility as far as customizable options. Why do

you have to buy a juiced-up beast just to get a 15 " screen?

So you hold the radio right up to the laptop and nothing?

Did you try both the high and low ends of the tuning dial?

Occasionally I " ve not noticed right away that the radio was

switched to FM.

Yes, I held the radio right up to the laptop - I may not have physically touched

it with the radio (for the most part), but I put the radio right up to it.

And it crossed my mind that there was a chance that my radio was on FM - but I

checked it yesterday (I had not touched the radio since my little field trip),

and it was indeed on AM.

Yes, I tried both ends of of the tuning dial - I often start on the low end, and

slowly move the dial (to see if I pick up any noise at *any* frequency) up

toward the high end - then slowly move it back down to the low end. I often

repeat the process. I did this several times - on maybe 3 or 4 different

laptops - and my radio just never " pinged " , so to speak - I got no sharp noises.

There seems to be too much of a pattern at this point for it to be a mistake or

a lucky coincidence. Two visits to the Apple Store - testing several laptops -

moving my radio up and down the dial many times over both visits - and not once

do I pick up any sharp responses from my radio? Yet I can walk into a Sears, a

Staples, a Best Buy - or just stay here at home and test my laptop or the new

LCD TV that my parents put in the den - and my radio picks up noise?

(Thankfully, the LCD TV is o.k. as long as the backlight is kept at maximum

level.)

It might be that we are getting two different results from the Apple computers

for whatever reason - but it's not because of any defectiveness of my radio or

testing methods.

I see. Your looking for sharp noises,

whereas I'm considering the very strong

static that the laptop produces. My Radio

Shack 12-586 starts to pick up static over

2 ft from the center of the keyboard,

whereas the Grundig mini 300 starts at

1 1/2 ft. That's with the laptop running

of the battery.

So the radio shack radio is a bit more

sensitive, however the tone of the Grundig

is much better and you can get a much

better sense of the severity of the

noise. It produces a much more menacing growl.

I used this laptop for a few minutes

yesterday and the ringing in my ears kept

me up most of the night. And I felt chest

pains the instant it was turned on for this

test. It also pegs my Trifield (100+ mg)

above the keyboard. The same goes for 99% of

the other available laptops equipped with

the new Intel i3, i5, and i7 processors.

This is not a good computer for the

hypersensitive, solid aluminum body and all.

Oh, wait - *static* is considered fair-game when it comes to evaluating RF

output? It has been my understanding that you listen for the sharp buzzes that

sometimes (or often, depending on the object) comes in over the static - not the

static itself. I don't even pay attention to the static when I'm doing these

tests - I just listen for distinct sounds (buzzes, " squeals " ).

Since I don't pay attention to static, I don't have a good sense for when a

nearby object is increasing the intensity of the static. But an object can be

considered an " EMF nightmare " based on the *static* it produces in a radio?

From a symptoms standpoint - maybe I'm engaging in some " wishful thinking " when

it comes to these Macbooks. I've found myself doing some rationalizing, having

thoughts like - " Well, these Macboooks have given me symptoms before - but this

time the symptoms aren't as bad... " Since my computer expertise is in the

gutter, and I don't trust myself to buy a computer that's not backed by a solid

warranty/tech-support plan - I feel locked into either a Mac or a Dell. Maybe

I'm repeating myself - but I feel like there are so many other considerations

than just e.s.-related things.

Theoretically, though - it seems that Macs are supposed to be relatively benign

- at least when compared to computers with similar specs. And the Core is - at

least the Core i3s and the Core i5s - use a 32nm manufacturing process, don't

they? Isn't that supposed to cut down on the emfs? By comparsion, the

processor in this old Dell laptop is 90nm (1.6 GHz Pentium M).

Do you know of any current laptops that might be better?
