You are welcome.
I occasionally ask for kindness in return in the form of cash or nest.
The next one due likely the week after next as Cabinet will decide on the removal of subsidies.
The news are not meant for information only.
They are meant for your action if you so desire.
You have and may exercise the democratic right not to defend your investment. biggrin.gif

As for the ultrasonic amplifier......
From recollection, it was previously shared.
Yes, there was no sound, from both the tweeters and the BH.
I emphasise....silence in the BH
The neighbour had a smile and the owner had the tear filled red eyes.
.......................................
The adventurous BH owner was last heard donating the ultrasonic amplifier to the Navy for submarine duty.....incase, sonar not included.
If not used as spare in the submarine it may be useful for imitating mating calls of the blue whales...with a penchant for politicians.

thks for the alert GEM/Hj Aziz

NST - Mar 31, 2010
Selayang Council proposes to amend local govt bylaws
After a series of workshops were conducted by the state's legal department and the views of state assemblymen, councillors and NGOs were considered, the draft amendments were presented to the full board for approval, before submission to the state government for endorsement and gazetting.
Razak said the policy changes included a fixed ceiling of RM10,000 on deposits payable for licence applications.
Previously, this was left to the council's discretion.
"In the area of enforcement, the bylaws stated that checks can only be done on premises licensed by the council. Now, we have the right to inspect all premises, whether they are licensed or not," he said.
Razak said there were now more detailed procedures for taking legal action on those who flout licensing procedures.
The compound rate for bylaw offences is now fixed at a maximum of RM2,000 per offence.

Before I am accused of spreading panic ...
Pls read Aziz's repro of The Star article & if you agree that
Heritage BHs facing impending doom!
May I request your urgent response to my question...
Does anyone of you either through your association or otherwise has firm knowledge in writing or in public announcements
if anyone in the industry has been consulted or in consultation with the authorities for all these regulatory changes?
Please urgently share here..
Even if your response is negative & you know of none, thks

The only way to test the ultrasonic amp before you buy is to play it with duress sound for 10 min and observe the response from the birds and then use the normal amp to play the duress sound again and observe again. Compare the results and post it in this forum  biggrin.gif
*
That was what I wanted to suggest initially, but....some reservations
Can an original track in the audible range be reproduced in the ultrasonic range by being played on an ultrasonic amplifier and vice versa?
Maybe the posting about the flop testing was cos' only the ultrasonic bit of the audible bird song was being played thus failed?
Need a audiophile to answer these questions biggrin.gif

In the event that it works at some point in future
Do we buy audible bird songs and play them on an ultrasonic amplifier that we cant hear OR
Do we buy an already ultrasonic track to play on an normal amplifier or ultrasonic amplifier
How would you know at the point of purchase that you have not purchased a blank CD or given a blank by accident?

Birds cannot hear high i.e. ultrasonic frequencies beyound the audible range of humans, above about 20 kHz, however birds do produce ultrasonic sound and some e.g. Capercaillies, produce very low infrasonic (below 40 Hz) frequencies.
http://psychology.exeter.ac.uk/lundy/bird_song.htm

This report conflicts with the 1 above.
http://www3.interscience.wiley.com/journal...869051/abstract

Still not conclusive then....
Maybe WaletJohor need to do some National Service for the industry and test it out.

what is the definition of urban areas? does it mean population density exceeding 40 persons per acre or 10,000 persons per sq kilometre of surrounding lands.
*
There's the reason behind my Qs if anyone knows of anyone who sits in consultation with the authorities in drawing up all these regulations.
I take it that no one knows for certain if there anyone from the industry in consultation with the authorities.
In that case, we have not been consulted!!!

We need the contents of the 1GP.
Are they going to hide behind legal procedural requirements to disallow us the contents of 1GP.
WildLife Bill need debating as such available in Parliament.
Is the 1GP related to national security that it can't be made available to the public?

It's been tried and tested !

Most modern audio amps, consisting of ic's and not valves, will respond to ultrasonic frequencies of 20khz to 40+khz. 
Very few adult humans can hear beyond 20khz.

Recordings on CDs can record beyond 20khz provided the original sound was recorded to include information beyond 20khz.

Microphones are usually designed to respond to no more than 40khz and usually it is the cheap mics. that use ceramic pic ups that will go that high.

The energy at high frequencies is short ranged.

Tweeters of the ceramic type can respond to play signals to about 40khz. That's the cheap made in china tweeter.

When an amplifier with a graphic equaliser is set to play bird calls only at the highest frequencies, the sound becomes very soft to human ears. The birds do seem to respond to this but not as well as when it is played normally. This is perhaps the range is nearer or  the birds cannot hear that well either.

With the above result, I never proceeded to true ultrasonic frequencies as it would be a waste of time.
*
tuckfook,
thks for the elaboration, most helpful.
Your posting does indicate a reduced reaction to ultrasonic sound in comparison to the audible, a reaction nevertheless.
Per yr posting you have set the equaliser to output just the ultrasonic then only a little of the full bird song will come through?
Is there a possibility that cos' only a small bit of the full bird song were played, explains the relatively little reaction?
Can the full bird song be manipulated correspondingly to generate a full ultrasonic bird song?
I am out of my depth on this so dun laugh so loud and injure yrself biggrin.gif .

I have never come across any audio file with ultrasonic format or extension. Most swiftlet's sound were either in .mp3 or .wav. So my guess is playing a normal .mp3 track in ultrasonic amp.
*
my 2 bit
sound are waves, so can be measured in hertz, kilohertz etc...
audible sound (what we human can hear) are in 1 range and ultrasonic (beyond human hearing) are in a different range
but both are sound and in IT-speak, both are audio files, as such I would assume they will be encoded the same format and thus bear the same extensions ie mp3, wav or whatever that applications and embedded systems can read and reproduce.

As tuckfook as pointed out, it all depends on wheter
1)ultrasonic sound was indeed recorded thru ultrasonic-capable mikes
2)your amp and tweeters are ultrasonic-capable to play and output the ultrasonic sound
I hope this helps.

Elaboration of my question in response to tuckfook's clarification
Say swiftlets songs consist of the 3 syallables
WAH TOLONG LU, LU TOLONG WAH, najis

WAH TOLONG LU, LU TOLONG WAH is in the audible range (ie we humans can hear and so can the swiftlets)
najis is in the ultrasonic range ie (we humans CANT hear but swiftlets can)

My question to tuckfook was, is there a possibility that past testing failed cos'
As the amp was set to output only the ultrasonic.....the tweeters played only..
najis, najis, najis....so the swiftlets did react a little but not as much as they would if the full range of the 3 syllables were played?

What if?????
WAH TOLONG LU, LU TOLONG WAH, najis are ALL manipulated into the ultrasonic range?????
Questions
1)Since all 3 are manipulated correspondingly to mantain the rhythm can any of the 3 syllables get BEYOND the swiftlets hearing?
2)Will the swiftlets still recognise WAH TOLONG LU, LU TOLONG WAH in ultrasonic for what it means in the audible range?

to work out
1)How to manipulate a proven pooling sound into the ultrasonic range?
Can one of the freeware audio app do it?

Yes you are correct that part of the birdsong is reproduced,  if the song has no "ultrasonic" birdsong, then none is recorded and therefore none is re produced.

Ultrasonic here is beyond 'most' human audible range. Dogs, and young humans, can still hear that range.  Not in the more technical sense as beyond complete human auditory range defined at 40khz and above.

We cannot convert normal audible to ultrasonic as then we would distort the original content. We can only play back the ultrasonic range if it exists.

Regenerating the birdsong completely into an ultrasonic range would seem ridiculous to me, akin to Sinatra singing in extremely tight pants straddling a bouncing narrow bar. Maybe the birds would find that interesting and amorous.


Added on May 24, 2010, 4:01 pmSound is basically in cycles per second.

If we compress it into half, ie the same number of cycles but in half the time or 2x the cycles per second, we actually double the frequency.

So, we can compress the music into one quarter and achieve very high frequencies but it'll sound silly, like donald duck having b..ls squeezed.

Most audio editing software will have a function to do this. You can keep compressing until it is totally inaudible to humans.

What I had done was to remove the audible to humans section and played the barely audible to humans remainder to the birds.

tuckfook,
Again thks.
It's clear now that it's a dead end.

Wah, away for a day so much heat generated-ah! biggrin.gif

On a more serious note.
On the Wild Life Conservation Bill 2010.
I do not know for certain how far and wide the reassurances given by certain folks that things are 'Semua-OK'.
I did get the forwarded reassurances that walit is taken off the Bill, though most of you who do read for info know that walit is never specifically mentioned in the Bill but nevertheless under Perhilitan's opaque licensing regime through indirect means.
Today I have received confirmation that the Bill IS going in for 2nd reading WITHOUT any changes NOR has any outstanding request for changes despite the assurance.

So for those of you who care enuff for some self help.
(1)Do return to my earlier post on the suggested letter to MP and send to your MP else it will get passed as it is by the week after next.
(2)I am looking for volunteer/s for a short translation of 1 page
from English to Chinese and BM
Pls PM urgently.


For those of you who continue to think that there's no sense in folks wanting to sink the boat they are in with you....
Think again, harder this time....to milk the golden goose, you don't kill it, you merely threatened it.
Not all are supposed to die, most are just wounded sufficiently to recover to crawl back into your rightful place.
Else there is nothing to milk.

Personally, this is very much like the ISA
When it was debated in Parliament all kinds of assurances were given that it will not be abused and was meant for terrorist.
It was then.......but NOW??????

Minister or designate has absolute discretion on what and when and how on licensing.
You kena 1 offence, you cannot be granted another license for 5 years max frm the time the court case ends.
What if your case gets dragged on for 10 tens which is not unusual!
So you think you can figure a way out ...think again, from harvesting to export is CONTROLLED.
Submarine? have you read and understood the penalties?
After your sentence you cant even be granted a loan to run a burger stall.
They can even tell you when to harvest (dun believe me , go and read the Bill)
Oh yes, there is a quota to licenses.

Last Sunday's Minister's statements are not sufficient to tell you enough?
Please folks, each of these are demanding a pound of flesh from you NOT KILL YOU, which was never the intention.
What more you have to deal with all those expected 1GP details and the 2 legged semut-semut that visit your BH anytime!
Makes you wonder if the whole secret of success of swiflet keeping is about knowing how to comply and play with semut-semut.
The worst realisation is WHAT DOES ALL THESE CONTRIBUTE TO THE ADVANCEMENT OF THE INDUSTRY?
In my previous life, these are known as BUSY WORK....ALOT OF WORK CREATED...but when you pull back and relook at the whole thing....IT HAS NO BENEFIT AT ALL TO US even after paying the pound of flesh.

best is to get people already in the association to bring your findings to the president and even the politicians.

Spot on, the choice before us, is between
1)prevention (dun let it happen at all) OR
2)mitigation (see how best and what one need to do to soften the blow).

I have touched base with the Fed association with the address provided here.
The correspondence went as far as asking me to introduce myself, which I did, since then it has been silent and my original questions remain unanswered.
"I wish to obtain the Fed Assoc feedback on the following:
1)Is the Fed association (in both the protem and formal capacity) a representative to the discussion with the authorities thus far?
2)What's the Fed Assoc assessment on the following matters in terms of
(o)benefits and
(o)negative points to BH operators
(a)1GP
(b)GAHP
©Wild Life Conservation Bill 2010
(d)new additional requirements from the Ministry of Health"


Anyway, I am still hoping for volunteers!

Guys, a note of caution.
the whole structure require additional strengthening cos, the soil, stones & water plus all the multi layers of special material for special drainage will exert a lot of stress on the structure. (read an article in National Geographic many moons ago) The special material for both drainage and leak proofing is not cheap, unless you plan skip that requirement and hand your NPs back to nature. But don't let my caution stop anyone if you have the building built to proper specs.

btw swiftlets and all the nice insects you imagine coming to your rooftop dont mix.
you tend to find more over weight swiftlets and less insects he he
"The walit in a farm like DQ provides a useful function in keeping the insect population low. We first noticed the walit when we were scratching our heads as to why our honey bees just keep on disappearing. Then we put two and two together. "
