Suggest audio-related topics for us to cover on our podcast, The Noise Floor!

I would be interested in a discussion about the sustainability of the IEM industry. Most products are made in China, what do we know about the working conditions and environmental impacts of all these companies?

I would rather pay 100 dollars for a sustainable product rather than 50 dollars for one that’s made using slave labor. I’m sure there are many who would. But I have yet to find any information about these companies that would help make better decisions.

Can we get Lachlan on the podcast? The Aussie guy, not the cable guy. #notmylachlan :)) I want to know what things he likes nowadays.

As for topic, I want to learn more about the history and development of the personal audio industry. Perhaps you can talk about significant milestones or important products in the past, or just your favourites. They can be speakers, headphones, IEMs, amplifiers, DACs, etc. Some of my favourite things of the yesteryears are the Stax SR-Omega, Shure SE846, Hidition Viento, Benchmark DAC1 with HPA2, Sony MDR-CD900, and Sennheiser HD 580 Jubilee. It’s also quite interesting to me that some IEMs are measured better on the 5128 than 711, like the Sony IER-M7. So perhaps revisiting older products wouldn’t be a bad idea for a standalone video or article in general.

Cheers guys! Looking forward to your next one.

Some ideas

  1. Some talk about how FR is related to musical notes. We often hear about how frequencies from a recording engineer’s perspective, ie 5k cymbal sizzle and 2k guitar presence, but if you think about it as it relates to notes instead, you run into some weird ideas. Some of the features you see on graphs look narrow enough that only one or two notes in a scale are going to be boosted or cut. When you take the idea that songs can be (or even shift) keys, you run into the idea that boosting a 5th scale degree vs a tonic might have a pretty wild effect on our perceptions of a song. Also, in the bass register, song key becomes extremely important as whether a note is in the sub bass, mid bass range, or is even audible has also affected how we feel about music.
    My question is as reviewers, how do you take these ideas into account? Do you think about song keys at all? Do you try to test devices using songs that hit notes that challenge or benefit from a particular tuning?

That’s an interesting thought, You sound like someone professionally involved with music.

Well sort of, I make software for musicians. I love making music but it’s purely a hobby.

Absolutely worth talking about. And yeah we do generally consider the spectral content of how various instruments are typically recorded, and how the playback equipment impacts the relationship between fundamental and harmonic tones for those instruments.

I first noted this a loooong time ago with Run DMC’s song “Down with the King” — the chiming background notes can fully disappear on some setups.

One thing to keep in mind is that when using pentatonic scales or many arpeggios you have 5 or fewer notes per octave so even a third octave feature might have a dramatic effect, and a sixth of an octave could be extremely targeted.

All ears if anyone has any topics they want us to discuss tomorrow. It’ll just be Resolve and I, though.

Probably too late now, but I’ll throw out some ideas…

  • I’d like to hear more about some of the new standouts for sound quality at Munich.

  • Also, what are your takes on listening/experiencing things vs. reading measurements/reviews? Which is more valuable in your opinion, and why? (Resolve commented on this briefly in a recent video.)

  • We know that synergies can exist between headphones and amps for frequency response. But what about synergies between different source components such as DACs, amps, and players? Can you also have a synergy between your player or DAC and headphone?

  • Related to the above, does it make more sense to buy synergistic combinations of gear, or to just stay neutral and noise/distortion-free all the way down the line? Certainly you want gear that plays nice from a power/impedance perspective. But what about other synergies related to “sound signatures”?.. Enquiring minds want to know.* :grinning_face:

  • Lastly, I am in the market for a new open-back headphone, priced around $100-300 (give or take). And trying to narrow down my options from an increasingly long list of newer and older contenders from a wide variety of mfrs. And would appreciate any fresh takes on this subject. Especially on new things that might have crossed your desk recently that are competitive with things like the Senn 6XX and HFM Sundara (and maybe better extended in the bass?).

*Hint: I generally don’t think it’s advisable to buy gear for synergistic qualities other than some basic impedance and power considerations.

As an aging newb audiophile but not newb listener of music, one of my concerns is how aging effects hearing, and consequently, listening enjoyment. I would be interested in what qualities a headphone/listening system might/should have, that could elevate ones listening experience. I think @generic might have possibly alluded to this in his post.

Judging from responses to my post regarding headphone suggestions for my personal situation, it would seem that many in the community are getting along in age, but not enthusiasm, and some guidance might be useful in terms of what qualities, features, specs, or whatever, to keep in mind when seeking equipment.

Hearing loss starts early in ones adult life. It’s gradual for most, to the point that you are not aware of what you are no longer hearing. It’s the old "you don’t know what you don’t know’, except it’s more like you don’t know what you’re not hearing. The analogy might be where someone upgrades from a cheap pair of department store headphones to a quality set like a higher end Senn, Meze, Audeze etc then suddenly realizes what they have been missing. Instruments they hadn’t heard before come alive … well, you get my point. Just as hearing aids help generally, how can our choices in audio equipment help musically?

Perhaps worth a chat as all of us are at one stage or another in our listening journey. Cheers and Happy Listening !

Some topics recommendations:

  1. The Impact of Listening Environments on Headphone Performance: Discussing how different environments (e.g., quiet rooms vs. noisy public spaces) affect headphone performance and listener perception.
  2. The Evolution of Wireless Audio Codecs: Analyzing the development of wireless audio codecs (like aptX, LDAC, AAC) and their impact on sound quality.
  3. Is wireless technology close enough to wired to call it good enough, or do we have a ways to go?
  4. The Influence of Cultural Preferences on Headphone Tuning: Examining how cultural differences influence preferences in sound signatures and headphone tuning.
  5. Sony WH-1000XM6 listening impressions.
  6. What are the signs to watch out for regarding this hobby going from a fun leisure activity to a potentially unhealthy obsession?

This is often known as the “synergy” of components, and in some quarters perceived improvements over neutral systems are described as “euphonics.” Given their recent advocacy for EQ/DSP, I’m not sure whether The Noise Floor crew is into this strategy. Some of the departed or infrequent site visitors previously discussed these or related concepts (e.g., @ProfFalkin; @Torq).

#1 sign of a hobby becoming an unhealthy obsession is watching 3 hours of live video consisting of 2-4 talking heads discussing your hobby. :stuck_out_tongue_winking_eye:

Hope @listener is feelin better.

Still tryin to think of other interesting topics. In the meantime though, I’ll re-up most of my previous suggestions.

A new target or pref bounds (or just some raw data!) based on in-ear measurements of neutral speakers in a semi-reflective room would be of great interest to me btw. Until then, I think the DF+SP model I’m currently using is probably the next best thing. Will try to keep an open mind though on whatever you’ve got comin. :grinning_face:

What is the RSS feed address link to the new podcast?

Generally, I’d agree. I’ve watched a large number of them though, largely because of limited mobility, a surfeit of time and a shortage of interesting ways to fill it. I did watch a 90-minute (-ish) video yesterday of Professor Brian Cox discussing what happens when matter goes into a black hole, the Einsteinian perspective, the Hawking theories, Hawking radiation, singularities and event horizions, distortion in (or flipping of) space/time, quantum mechanics and so on. Brilliant video, IMHO, despite me knowing nothing, or less, about astrophysics.

You think watching a headphone discussion is weird? What does that make me … (rhetorical question, I’ll add quickly). :smiley:

Here’s a question for you:
Which products would you recommend to someone who you know is going to use EQ and knows what they’re doing with it?

I liked the discussion on different audiophile terms. Maybe in future streams you could discuss this further.

How do you understand the different terms and how do they correlate to FR?
