Date: Tue Sep 10 07:33 Gerhard Martini (py5gm@netpar.com.br): Success for you, the information is very important. Date: Mon Sep 16 14:02 Sanjay Chiniwala (snc9342@tam2000.tamu.edu): It is an excellent idea to put a section for introduction to the Digital Recording Techniques. Thank you very much for all the information and keep up the good work. Date: Wed Sep 18 06:24 Joe High (KJ2Smooth@AOL.COM): PLEASE SEND ME SOME INFORMATION ON STUTTERING, I MYSELF AND A STUTTERER SO PLEASE HELP OUT A FELLOW STUTTERER. Date: Wed Sep 25 22:20 Bill Chess (6571@mne.net): I'm interested in your audio CD. But going through the hassle of figuring out how to pay you is just not worth my time. International wire fund transfer- cumm on- the last time I tried that the bank wanted a $25 fee just to consider it. Either take a personal check on a US bank for US funds and you figure out how to cash it or set up a visa account and take my visa number. Otherwise you can forget about the US market. Sorry to be so blunt, but that's the way it is. Bill Date: Thu Sep 26 19:19 Digital Recordings - Marketing Team (digital@ra.isisnet.com): Bill, we are in the process of setting-up VISA account. It should be available in couple of days. Best regards. Date: Mon Sep 30 10:12 Toby Ovall (ie9340@malmo.lth.se): Thanks for the info on digial recording techniques. Date: Wed Oct 2 11:12 Zbigniew Maciejewski (ZbiMac@Melbpc.org.au): Something New something Good and I hope you will do good JOB Thankx & All the best for each user from Zbimac&melbpc.org.au P.S. if you would like to you can send me ANY Email OK ? Date: Wed Oct 23 15:08 Bob Maes (RAMaes@aol.com): First heard about your Audio-CD on a broadcast of the "As It Happens" show on PBS. I'm interested because, at the age of 61, I think I'm beginning to have some hearing difficulties (my wife thinks so too) and welcome some means of objective testing. I tracked you down by calling the local PBS station where I heard the show. They gave me a phone # for the "As It Happens" producer in Totonto (Brooke Forbes). Her information was limited to a phone number (which was incorrect), your e-mail address (which fortunately was OK), and no address. Thanks for your prompt answer to my e-mail. I've just completed placing my order from your web page. You might wish to contact Ms. Forbes and give her your full address & correct phone number in the event she receives any more inquiries via the route I took. Regards; Bob Maes, Glen Ellen, CA, USA. Date: Fri Oct 25 19:06 Waldek Galka (galka@symbol.com): I am impressed ! Date: Mon Nov 11 12:16 Jont Allen (jba@research.att.com): I like what you have done here. I think you need to add some references to allow people to read more about this, if they want to. I agree that the public needs to be more aware of the harmful effects of loud sound. Date: Fri Nov 22 06:58 Kjell Ove Kjølaas (kjell.o.kjolaas@informatics.sintef.no): The DSA looks very interesting and I am pppresently searching for more information. Date: Fri Nov 22 15:14 Ronaldo Richard (ronaldo@nbnet.nb.ca): Looks really interesting. I own a full Pro-Tool systeme with Logic Audio programme. I would really like to get the more information as possible on recording techniques... Wood you be kind to reply to me and even give me some pointers??? Date: Fri Nov 29 23:33 tadt (tadt@total.net): Hi, I would like to listen to samples of your products, before I'll buy it.. Tx Tadt Date: Sun Dec 8 12:03 Marcos Gridi Papp (gridi@cesar.unicamp.br): Thank you for the information! Where can I find more on the Nyquist theorem and the relations between sampling rate and higher frequency? Date: Mon Dec 9 06:29 Beng Paredes (beng@linette.eee.upd.edu.ph): Hi! I'm doing a research on digital voice filtering in tapes, and I was wondering if your company could help me. Would you be so kind to send me some information on this? Please send me the reading materials in less technical terms. Thank you very much and I will look to your favorable response. Beng Paredes BS Electrical Engineering University of the Philippines Digital Signal Processing Lab 3rd Fl. NEC, UP Diliman Diliman, Quezon City Philippines, 1101 Date: Sat Dec 21 00:34 Peter Guiod (PETER@SPEECH.MIT.EDU): I am interested in your CD ROM re: audiometric testing, though this should never take the place of a formal audiological exam by a licensed audiologist. But it would be very handy for audiological screenings that many speech pathologists are often tasked to do. I am also very interested in your Function Generator software; are you working on porting this to a Windows platform anytime soon? Also, could you send information regarding ordering this software? Thanks very much. Peter Guiod, Mass. Inst. of Technology Date: Thu Jan 9 12:40 Daniel Hicks (950034@adhs.ednet.ns.ca): Hello I am currently doing a research project in a computer course at my high school. I am wondering if you could send some technacle info on computer digital recording. The information would be very valuable for my personal interests, and for my research. Thank You.

Date: Thu Jan 23 04:30 Norman Kropman (Norman.K@pixie.co.za): Well presented info. None of which may be new but it is ignored by most authorities who obviously do not understand the implications, or have vested interests to cause them to ignore it! Have you any info or comment on digital hearing aids and their efficacy compared to the analogs on the market? Oticon, Widex an maybe Siemens seem to have them. Would be grateful to hear from you as someone who truly understands sound and hearing. Date: Mon Feb 3 01:02 John Storyk - Walters-Storyk Design Group, Inc. (john@wsdg.com): Nice work. Your conclussions about B & K vx. Radio Shack are quite accurate. I use them both! Check out our home page - www.wsdg.com - possible link. Good luck. JOHN Date: Wed Feb 5 22:28 Karl Pearsons (kpearsons@bbn.com): Sounds interesting as a screening tool and also as a monitor of changes in hearing level. Date: Thu Feb 6 16:34 W.B. "Barry" Hoobler (barry@wanweb.net): Thanks for takeing the time to put this info. together. Date: Sat Mar 22 23:11 FELIX CRUZ (felixc2@flash.net): thanks for the info. presently working with hearing impaired and your info will help.thanks Date: Sun Mar 23 23:21 jim gray (jamesg6@ix.netcom.com): Thank you for the comparison on the Radio Shack SPL meter. I am using it as a basic SPL meter for a functional test on a product we build for a third party. To know that it is well within the parameters required for our test is very reassuring. I look forward to use of your website and potentially your products as I learn more about them. Thanks again... Date: Mon Mar 24 16:29 Joe Prince (joe3of5@aol.com): I am fascinated with your work on the Digital Speech Aid. I am a stutterer and have tried many things but none with great success. I must have missed in your DSA Web information how a stutterer could find out the price and availability of the DSA (or better yet, any clinical trials of smaller future versions of DSA). Any information would be greatly appreciated. Sincerely, Joe Prince joe3of5@aol.com . Date: Wed Mar 26 00:23 Karl Keefer (dogfight@ix.netcom.com): My experience with the Radio Shack digital SPL meter were similar to yours. I am a metrology technician with the USAF, and had access to General Radio and B&K audio calibration devices while stationed east of Los Angeles. I found the meter to be accurate to well within the specification, mostly internal display noise of +/- 1 least significant digit @114dB. This is the audio bargain I recommend to any one with a recording studio and undamaged ears. Date: Thu Mar 27 01:35 Mont Stong (audin2hrg@aol.com): I'm an audiologist and came across your CD today. I thought this was a great, self test, screening tool. Sort of the 90's version of the phone screening. I hope this CD is being used as an indicator of a potential hearing loss and not as a diagnostic tool. Your web site was incorrect on your brouchure that's enclosed in the CD case. Date: Thu Apr 3 17:19 Lydia Watkins (mongo1@mn.uswest.net): This is very helpful for our science report!!!!!! Date: Thu Apr 17 16:58 Charles S. Post (post9286@ginko.ait.fredonia.edu): I enjoyed your scientific tests between the B&K and Radio Shack SPL meters. I am a recording student at Fredonia State and have been reluctant to purchase the RS model, fearing it may be grossly inaccurate. However, after seeing your results, I may have one by weeks end! Thank you... I'll be back! For more info concerning Fredonia's SRT program, contact the AES Fredonia Section at (716) 673-3307. -CSP, AES Fredonia Section Chairman Date: Sat Apr 19 09:25 Chriss (chriss@webtv.net): UNBELIEVABLE! I refer to your test results with the "Radio Trash" SLM. Hard to believe rhat something under $100 can compete with a $5000 unit. Thank you. Date: Sat Apr 19 09:35 Chriss (chriss@webtv.net): I've been servicing and selling audiometers throughout New England for the past 14 yrs. I am very interested in your digital audiometers. Is there anymore info. that you can email me? What type of transducers does it use? Date: Sun Apr 20 15:48 Satyendra Kumar (guptas@ecsis.net): I am an audiologist and I also edit `Hearing Aid Journal' published from New Delhi, India. I would be interested in getting complete details about hearing testing - audio CD and audiometer software. This product may have good potential in many developing countries.

Dobkin (Rhythm8@SoCA.COM): Hi - I'm an audiologist with a private practice (Hearing Enhancement Center) in Southern California. I have long maintained that temporal resolution of the auditory system is something we (audiologists) should be evaluating. Digital technology is providing the means for assessing and, hopefully, rectifying temporal resolution impairment in the human auditory system. I am most interested in your software based audiometer with its extended testing capabilities (temporal resolution, etc..). Bravo for your contribution! Date: Tue Apr 22 21:09 BJanisch (bjanisch@lcc.net): Excellent work! Amazing how some people can write on a technical subject so clearly. Thanks for the knowledge and I'm looking forward to more of your work in this field. Date: Tue Apr 29 14:59 JEFFREY S TROMPETER (DJX19@webtv.net): I HAVE BEEN A NIGHTCLUB DJ FOR 16 YEARS AND IVE STARTED TO LOSE ABOUT 15 PERCENT OF MY HEARING. I PURCHASED YOUR SOUND METER TO KEEP THE LEVEL IN THE ROOM TO NO MORE THAN 90 DECIBALS. IT IS A FANTASTIC PIECE OF EQUIPMENT! EVERY NIGHTCLUB SHOULD PURCHASE ONE. Date: Wed May 28 17:27 Bryan Weimert (weimertprod@soundcity.net): A quick 'hello' and a 'Job Well Done' ! Date: Wed May 28 17:31 Bryan Weimert (weimertprod@soundcity.net): A quick 'hello' and a 'Job Well Done' ! Date: Mon Jun 9 12:57 Steve Privett (QED Audio UK) (steve_privett@Compuserve.com): Your comments on the effect of prolonged noise exposure are most welcome. Unfortunately hearing loss is not visible; if it were we would all be shocked at the extent of this modern day disability. Public awareness of the causes of deafness are key to our keeping a quality of life! The very best of luck with your CD. Date: Wed Jun 11 19:00 Kevin Becka (kbecka@aztec.asu.edu): Very nicely done! I've linked your page to my own recording page at http://homerecording.miningco.com .... Keep up the good work! Date: Wed Jun 18 17:55 Mike (dragon6767@aol.com): Please send me info on the dsa Date: Wed Jun 25 07:20 Dumisani Xhakaza (dxhakaza@bullion.org.za): right information at the right time. Could you please post more info on recording studio designs. Phambili! Digital Recordings! Phambili! Date: Wed Jul 2 00:11 K. Hamilton (knhamilton@coastnet.com): Thanks for the valuable information about the harmful effects of loud noise. The urban soundscape is becoming unbearable. Research has shown that children raised in noisy environments are slower learning to talk and to read. We need to make more people aware of the issue. Keep up the good work! Date: Sun Jul 13 17:31 Brian Frost (bmf702@nwu.edu): I'm just wondering if anyone there has any helpful hints pertaining to a project I am working on. A couple of months ago I was doing some recordings with a B&K 5000 onto a SGI which was sampling at almost 200k. I found that the monitor was making a 70-90 dB whine at 37kHz. I thought that was interesting. So, I plan to take some recording equiptment with me to the field and record some more stuff. The B&K (I'm told) can record upwards of 100kHz. The problem is that all the dat's we have access to can record only as high as 48k/samples which will only allow for 24kHz signals to be recorded. I've heard pioneer makes a dat that samples at 96k. I just don't want to lug the SGI around. The research is going to be used to determine whether further study on the effects of ultra-sonic exposure on hearing (such as in the case of people using SGI monitors which might be making loud noises which we jsut can't hear) and the recordings will be used for a musical composition once we have pitch shifted them. Any info you think is pertainant will be appreciated. Brian Frost (847)328-0695 bmf702@nwu.edu Northwestern University Date: Sun Jul 20 10:29 adnan rashid (ar14@cs.uow.edu.au): can you give me information that from where in sydney I can buy this machine. How much is the cost for one machine Date: Wed Jul 23 20:18 Ned Heidner (sheldon1@hotmail.com): I never went to school (but I want to) to get a piece of paper that says I know what I am doing. But you left out a third party. Those of us who are responsable and who are willing to learn from those people who are responsable, and use that information which that piece of paper says that they know. In my humble opinion it is not just the education that make a difference, but the responsibility of the person in dealing with the power that we are given Date: Tue Jul 29 13:43 Marshall L. Sponder (mlsiggaes@aol.com): I enjoyed talking to Mark Roland; your company is very cutting edge. I am looking forward to trying your audiogram via CD.
