Review of Kemo Listening Stethoscope

IMAG2546-1-1

Elec­tronic kits can be worth­while for us as field record­ing geeks. This time I bought the Kemo kit for a Lis­ten­ing Stetho­scope since I was inter­ested in ampli­fy­ing the soft­est of sounds, such as wind blow­ing through the trees. For the price of 11.80 €, I was skep­ti­cal at first but with a lit­tle sol­der­ing the board works just fine. The offi­cial prod­uct descrip­tion is quite shady when they say that their device enables you to lis­ten through walls, etc. Appar­ently some­body lacked the fan­tasy of doing some­thing legal with the stethoscope.

How­ever, if you look for a quick and dirty record­ing of soft sounds, the Kemo Lis­ten­ing Stetho­scope is a good choice, since the IC’s triple op amp enhances ordi­nary sounds very well. But still, don’t expect crys­tal clear one-to-one real­is­tic record­ings, you need to be able to either fil­ter out or ignore the high fre­quency noise. Another chal­lenge is to keep the right dis­tance between mic and head­phones because the device is so sen­si­tive that it is prone to feed­back. Need­less to say, you’ll only get a mono recording.

For you to get an impres­sion, I made a very dirty record­ing out of the win­dow with some­body prac­tic­ing the vio­lin next door. I con­nected the head­phone out­put with a male mini jack that went into the line in  of my old Tas­cam DR-07.

Master’s Thesis: A bang, a Hiss, and a Sigh

Abstract. This the­sis exam­ines the rhythms and sounds of embod­ied work processes by com­pos­ing with field record­ings. It attempts to give an overview on the basic dis­course about the use of field record­ings. Sev­eral dif­fi­cul­ties of defin­ing the field are pointed out and rep­re­sen­ta­tional prob­lems are dis­cussed. In order to derive a con­cept of the sounds of work processes, the sound­scape of the indus­tri­al­ized world is described. The prac­ti­cal part con­cerns a case study in the Port of Rot­ter­dam.

Can you please…? Experiment

There are spaces where com­mu­ni­ca­tion takes a lot of effort, which is often due to cer­tain acoustic fea­tures. To pro­vide evi­dence and details, a mea­sure­ment was per­formed. In this case the acoustics of a room were approached by ana­lyz­ing its capac­ity to trans­mit speech and hav­ing a closer look at rever­ber­a­tion time and low fre­quen­cies. arti­cle

 

Eduard Hanslicks Musikästhetik

In his habil­i­ta­tion “Vom Musikalisch-Schönen” (On the musi­cally beau­ti­ful) of 1854, Hanslick dis­cusses the aes­thet­ics of music. His work is impres­sively anti-romantic and elo­quently fights against the ideas of his time.
My essay intro­duces Hanslicks ter­mi­nol­ogy and jux­ta­poses it to the philo­soph­i­cal ideas of the 19th cen­tury. A con­clu­sion of how to apply Hanslicks the­ory to con­tem­po­rary music is given.

Sprechende Instrumente

The results of phono­log­i­cal research in the 19th cen­tury helped cre­ate syn­thetic speech. In the 20th cen­tury dig­i­tal sig­nal pro­cess­ing made it pos­si­ble to apply this knowl­edge to elec­tronic music. The essay gives an overview about the tech­niques involved and briefly dis­cusses com­po­si­tions of Paul Lan­sky and Klarenz Bar­low.
